TJA1044GT

TJA1044GT - High-Speed CAN Transceiver, SO-8 | NXP

The NXP Semiconductors TJA1044GT is a high-speed Controller Area Network (CAN) transceiver with Standby mode, providing the physical interface between a CAN protocol controller and the differential two-wire CAN bus. It is housed in an 8-pin SO (SOIC-8) package, supports data rates up to 5 Mbps for CAN FD, and is qualified to AEC-Q100 Grade 1 for automotive body and safety applications. A CAN transceiver is a physical-layer (PHY) device that translates the digital transmit/receive logic signals from a microcontroller or CAN protocol controller into the differential voltage levels defined by ISO 11898-1 for the CAN bus. Within the broader hierarchy, a CAN transceiver sits between the data-link layer (handled by the protocol controller) and the physical differential bus; in an in-vehicle networking stack it is part of the in-vehicle communication (IVN) physical layer alongside LIN, FlexRay and Ethernet PHYs. Key features include very low standby current (typical 5 uA) for always-on automotive networks, an autonomous standby/sleep mode that wakes the device when bus activity is detected, excellent EMC performance optimized for automotive bus nodes, and full ISO 11898-2 (and ISO 11898-5 for the low-power variant) compliance. The Mantis family architecture used across the TJA1044 family provides tight parametric matching between variants, simplifying multi-rail ECU designs. The TJA1044GT is part of NXP's Mantis CAN transceiver family and is widely used as a drop-in replacement or alternate for the legacy TJA1050/TJA1040 in next-generation ECUs. The 8-pin SO (SOIC-8) footprint with industry-standard pinout (TXD, GND, VCC, RXD, VIO/n.c., CANH, CANL, STB) allows easy migration from older TJA1040/TJA1050 designs to modern CAN FD networks. The part operates from a single 4.75V to 5.25V supply on VCC. Typical applications include automotive body-control modules (BCMs), gateway ECUs, infotainment and cluster CAN nodes, chassis and powertrain CAN nodes requiring low quiescent current, and industrial CAN networks. The selective wake-up capability also suits CAN-based partial networking where the ECU must remain in low-power while monitoring the bus for a wake frame. When designing with the TJA1044GT, place a 100 nF decoupling capacitor close to VCC (pin 5 on the GT variant, which has no VIO pin) and ensure the split-termination (typically 60 ohm with two 30 ohm resistors and a 4.7 nF capacitor to ground) is correctly placed for proper recessive-level biasing. The STB pin must be tied to logic-low for Normal operation.

TJA1044GT-3Z

TJA1044GT-3Z - High-Speed CAN Transceiver with Standby Mode | NXP

The NXP TJA1044GT-3Z is a high-speed Controller Area Network (CAN) transceiver with Standby mode, housed in an 8-pin SO (SOIC-8) package, designed to interface a CAN protocol controller with the physical two-wire CAN bus. It belongs to the Mantis family of high-speed CAN transceivers from NXP Semiconductors, providing differential transmit and receive capability between a microcontroller and the CAN bus. The device operates from a 4.75V to 51V supply range and supports data rates up to 1 Mbit/s per ISO 11898-2, including CAN FD (Flexible Data-rate) frames in the arbitration phase. A CAN transceiver is a physical-layer (PHY) interface IC that bridges the digital logic domain of a CAN protocol controller (typically embedded in a microcontroller) and the differential voltage-domain wire bus. In the broader IC hierarchy, a CAN transceiver belongs to the Interface IC category, which also includes LIN transceivers, RS-485/RS-232 transceivers, and I2C/SMBus repeaters; together these form the connectivity layer of an automotive or industrial electronic control unit (ECU). The TJA1044GT-3Z additionally integrates an autonomous standby mode and a STB pin for selective wake-up, enabling low-quiescent-current operation in always-on automotive body-network ECUs. Key features of the TJA1044GT-3Z include ultra-low power consumption in standby mode, very low electromagnetic emission (EME), high electromagnetic immunity (EMI), and integrated TXD dominant-timeout protection. According to the manufacturer datasheet, the transceiver is designed for high-speed CAN applications in the automotive industry and provides differential transmit and receive capability between a microcontroller and a CAN bus. It supports both 3.3 V and 5 V microcontrollers when used in the proper VIO configuration (variant -3 has the VIO supply pin). The TJA1044GT-3Z uses a bipolar process with integrated ESD protection on the bus pins (typically ±8 kV HBM, ±6 kV IEC 61000-4-2 contact discharge per the datasheet). The architecture separates the transmit data path (TXD) from the receive data path (RXD) and includes slope control to limit the slew rate of the CANH/CANL edges, reducing radio-frequency emissions. The standby mode reduces current consumption dramatically so the ECU can satisfy automotive quiescent-current budgets when the ignition is off but the network must remain wake-capable. Typical applications include automotive body and comfort networks (door modules, seat controllers, mirror modules), powertrain ECUs (where CAN FD is required for sensor aggregation), chassis and safety CAN nodes, industrial CAN gateways, and CAN-bus diagnostic interfaces. The wide supply range (down to 4.75 V and tolerant to load-dump events up to 51 V) makes the TJA1044 directly compatible with 12 V automotive battery rails without external protection components. When designing with the TJA1044GT-3Z, place a 100 nF decoupling capacitor on VCC as close as possible to the pin, and follow the datasheet's recommendations on CAN bus termination (typically 120 ohm at each end of the bus). Do not leave the STB pin floating; tie it to GND for normal operation or to the microcontroller for wake/sleep control. Always respect the maximum bus voltage rating, especially in 24 V truck systems where the load-dump transient can exceed 51 V if the suppression is inadequate.

TJA1044GTJ

TJA1044GTJ - 5Mbps CAN Transceiver, 8-SOIC | NXP

The NXP Semiconductors TJA1044GTJ is a high-speed CAN transceiver with standby mode, providing one transmitter and one receiver for a two-wire Controller Area Network bus. It supports a data rate of 5 Mbps and a 4.75 V to 5.25 V supply range in an 8-pin SOIC surface-mount package. The transceiver includes a 300 mV receiver hysteresis and is intended to connect a CAN protocol controller to the physical CAN network. A CAN transceiver is the physical-layer interface within a Controller Area Network system. The protocol controller creates and interprets CAN frames, while the transceiver converts those digital signals into differential bus levels and converts received bus levels back into controller-compatible logic. CAN transceivers therefore belong to the hierarchy of interface IC, communications transceiver, CAN interface, and semiconductor. Verified device data identifies the TJA1044GTJ as a one-driver, one-receiver, half-duplex 5 Mbps CAN interface with standby mode. Its 8-SOIC package supports automated surface-mount assembly, while the 300 mV receiver hysteresis provides noise margin around the receiver switching threshold. The 4.75 V to 5.25 V supply range permits use with conventional regulated 5 V digital systems. The TJA1044 belongs to NXP's Mantis high-speed CAN transceiver family and targets automotive networking. Its CANH and CANL bus-side interface must operate with the protection, termination, routing, and common-mode strategy required by the target vehicle network. Standby mode provides a means to reduce participation when the node does not require normal bus operation, but the system designer must confirm all wake-up behavior from the complete manufacturer documentation. Typical uses include body-control modules, automotive comfort systems, powertrain-adjacent controllers, gateway nodes, and industrial CAN equipment connected to 5 V logic. A CAN controller, crystal or clock source, decoupling network, bus termination, and connector are normally placed around the transceiver according to the reference design and system requirements. Design care should focus on bus-layout symmetry, short ground returns, correct split termination, compliant common-mode protection, and validation of standby-state timing. The CAN wires should not be routed as ordinary unprotected low-speed signals because fast edges and faults can exceed expectations outside the transceiver operating envelope. This page consolidates verified manufacturer and distributor information, separates known TJA1044GTJ characteristics from missing data, and evaluates candidate replacements conservatively. It is intended to add sourcing context and design guidance without presenting unsupported electrical limits or unverified cross-brand pin compatibility as fact.

TJA1044GTKZ

TJA1044GTKZ - High-Speed CAN Transceiver, 5Mbps, HVSON-8 | NXP

The NXP TJA1044GTKZ is a high-speed Controller Area Network (CAN) transceiver from the Mantis family, providing the physical interface between a CAN protocol controller and the two-wire CAN bus, packaged in an 8-pin HVSON (3mm x 3mm) with an exposed thermal pad. It supports data rates up to 5 Mbps in CAN FD (Flexible Data-rate) networks and features a low-power Standby mode for quiescent current reduction when the bus is idle. A CAN transceiver is a physical-layer device that converts the digital transmit/receive signals of a CAN controller into the differential voltage levels required by the CAN bus standard (ISO 11898-2:2016). As a member of the high-speed CAN transceiver category, the TJA1044 sits at the bottom of the in-vehicle networking hierarchy: microcontroller -> CAN controller (typically integrated in the MCU) -> CAN transceiver (TJA1044) -> differential CAN bus. It is foundational to automotive and industrial communication networks where reliable, deterministic messaging is critical. Key features include a very low-current Standby mode with remote wake-up via a wake-up pattern (WUP) recognition per ISO 11898-2:2016, bus-fault detection and protection against -27 V to +40 V automotive transients, thermal shutdown, and an undervoltage detector on VCC and VIO. The transceiver operates from a single 5 V supply (VCC), with a separate VIO pin for direct interfacing to 3.3 V or 5 V microcontrollers without level shifters. The TJA1044 uses a fully ISO 11898-2:2016 compliant driver and receiver with dominant-timeout protection to prevent a faulty controller from permanently clamping the bus. The integrated slope-control function (via the STB/NRM pin) and low Electromagnetic Emission (EME) design simplify EMC compliance in dense automotive modules. The exposed thermal pad (EP) of the HVSON-8 package is essential for dissipating heat during sustained dominant transmission, ensuring reliable operation across the -40 C to +150 C automotive Grade-1 temperature range. Typical applications include body control modules, gateway ECUs, powertrain ECUs, battery management systems (BMS), ADAS sensor ECUs, industrial CAN nodes, and telematics control units. Its 5 Mbps capability makes it suitable for CAN FD networks carrying larger payload data, while Standby mode enables CAN partial networking for ECUs that must wake only on recognized WUP messages. When designing with the TJA1044, terminate the bus with a 120 ohm split-terminator network (RT = 60 ohm + 60 ohm + 4.7 nF common-mode cap) rather than a single 120 ohm resistor, which improves EMI/ESD immunity and DC stability. Place a 100 nF decoupling capacitor close to VCC and ensure the exposed pad is soldered to a sufficient copper pour for thermal dissipation.

TJA1044T/1Z

TJA1044T/1Z - High-Speed CAN Transceiver, 1Mb/s, 8-SO | NXP

The NXP TJA1044T/1Z is a high-speed Controller Area Network (CAN) transceiver from the Mantis family, providing an interface between a CAN protocol controller and the physical two-wire CAN bus in an 8-pin SO (SOIC-8) package. It supports CAN data rates up to 1 Mbit/s and reliable communication in the CAN FD fast phase at data rates up to 5 Mbit/s, and it implements the CAN physical layer defined in ISO 11898-2:2024 third edition and SAE J2284-1 to SAE J2284-5. A CAN transceiver is the physical-layer device that sits between a microcontroller's CAN protocol controller and the differential CANH/CANL bus wires. It translates the controller's digital transmit (TXD) and receive (RXD) signals into the dominant/recessive differential voltage levels required by the ISO 11898 standard, while providing ESD protection, bus fault tolerance, and common-mode rejection. The TJA1044 belongs to the higher-level hierarchy: CAN transceiver → automotive network interface IC → in-vehicle networking → automotive power management, and is widely used wherever an MCU must communicate over a robust, differential bus. Key features include very low standby current with wake-up capability, an internal slope-control mechanism that reduces electromagnetic emissions, and excellent EMC performance that allows removal of common-mode chokes. The device provides high ESD robustness on the bus pins (typically ≥8 kV HBM) and is specified over the -40 °C to +150 °C automotive temperature range. A dedicated standby mode reduces quiescent current while still monitoring the bus for wake-up activity, making the TJA1044T/1Z well suited for always-on automotive networks. The implementation uses NXP's proven BiCMOS process and an advanced differential transmitter with tightly controlled edge symmetry to minimise radiated emissions. Combined with an integrated split-pin concept (the SPLIT output stabilises the recessive common-mode voltage of the bus) and a wide common-mode range for CANH/CANL, the design delivers high ElectroMagnetic Compatibility (EMC) margins even on long cable backbones. Typical applications include high-speed CAN body and chassis networks, powertrain ECUs (where the part operates at -40 °C to +150 °C), CAN nodes for body-control modules (BCMs), gateway nodes between CAN and CAN FD buses, and industrial CAN-FD field-bus nodes in vehicles, trucks, agricultural equipment, and forklifts. When designing with the TJA1044T/1Z, place a 100 nF decoupling capacitor as close as possible to the VCC pin and follow the bus-layout recommendations in the manufacturer datasheet. A split termination (typically 60 Ω between CANH and CANL plus two 30 Ω resistors to ground through a 4.7 nF capacitor, or referenced to the SPLIT pin) significantly improves EMC behaviour and should not be omitted on long stubs. This page combines manufacturer-anchored specifications, same-family drop-in alternatives, comparison data and PCB-level design notes that go beyond a single distributor product listing.

TJA1044VTZ

TJA1044VTZ - 5Mbps CAN Transceiver | NXP | Automotive

NXP Semiconductors TJA1044VTZ is an automotive high-speed CAN transceiver with standby mode, one transmitter, one receiver, and a maximum data rate of 5 Mbps in an 8-pin SOIC package. It operates from a 4.75 V to 5.25 V supply, supports a half-duplex CANbus connection, and has a junction-temperature range of -40°C to 150°C. A CAN transceiver is the physical-layer interface between a Controller Area Network protocol controller and the differential two-wire CAN bus. Within the hierarchy of CAN interface ICs, transceivers convert controller logic levels into bus voltages and convert received bus levels back into digital RXD signals. The TJA1044 belongs to NXP's Mantis high-speed CAN family and is intended primarily for automotive electronic systems. Key verified characteristics include 5 Mbps operation, normal and standby operating modes, 300 mV receiver hysteresis, 4.75 V to 5.25 V supply operation, and an automotive AEC-Q100 classification. The single-transmitter, single-receiver arrangement supports half-duplex CAN communication through one shared bus interface rather than providing separate independent send and receive channels. The TJA1044 family interface uses differential CANH and CANL bus connections to reject common-mode noise while communicating over a noisy vehicle network. Its 300 mV receiver hysteresis helps determine valid bus signaling, while standby mode provides a control path for reducing activity when the node is not participating in communication. Exact loopback, propagation-delay, bus-fault, and electrical-characteristic limits are not available in the supplied snippets and must be confirmed in the manufacturer datasheet. Typical uses include automotive body-control modules, powertrain controllers, gateway electronics, comfort systems, and other ECUs connected to high-speed CAN networks. A controller such as a CAN-capable microcontroller connects through TXD and RXD, while TJA1044VTZ handles the physical bus. System designers must verify bus topology, termination, transceiver timing, fault behavior, standby polarity, and thermal performance against the complete datasheet. For PCB implementation, use the manufacturer reference layout and route CANH and CANL as a tightly coupled differential pair away from switching nodes and high-current paths. Place protection and common-mode-choke components where their impedance and capacitance remain compatible with the target CAN bit rate and network topology. This product record consolidates verified manufacturer and distributor facts, source links, practical design guidance, and clearly marked missing electrical details. It distinguishes documented TJA1044VTZ characteristics from parameters requiring review of the full NXP datasheet before release to production.

TJA1046TKZ

TJA1046TKZ - Dual 5 Mbps CAN Transceiver | NXP

The NXP TJA1046TKZ is a dual high-speed CAN transceiver in a 14-HVSON surface-mount package, integrating two independent interfaces between CAN protocol controllers and physical two-wire CAN buses. Each channel supports differential transmit and receive operation up to 5 Mbps and includes standby mode for systems requiring controlled low-power operation. The -5.25 V part number identifies the NXP ordering variant associated with the provided TJA1046TKZ product data. A CAN transceiver is an interface IC within the network-interface and automotive electronics hierarchy. It converts logic-level TXD and RXD signals from a CAN controller into differential bus voltages, while converting bus levels back into logic-compatible receive signals. A CAN controller handles frames, arbitration, acknowledgments, and protocol error management; the physical-layer transceiver connects that controller to the wired CAN-Bus network. The verified product information identifies two fully independent TJA1044GT transceiver sections, high-speed automotive CAN operation, differential bus signaling, and standby capability. The dual-channel architecture reduces the component count where two CAN nodes or bus segments must share one physical PCB area. The 14-HVSON package is only 3 mm by 4.5 mm according to the DigiKey listing, supporting compact automotive and industrial electronics layouts without combining two separate transceiver packages. TJA1046TKZ is appropriate for automotive body, chassis, powertrain-adjacent, and industrial control networks when two high-speed CAN physical-layer interfaces are required. Dual-channel integration can simplify component placement and reduce PCB routing effort, although each channel still requires correct bus termination, common-mode behavior, electromagnetic-compatibility layout, and decoupling. The CAN bus must use twisted-pair wiring and appropriate 120-ohm termination where specified by the network design. The principal design consideration is to follow NXP's specified pin, supply, ground, input, output, and exposed-pad connections exactly. Each transceiver must be placed close enough to its connector or bus interface for short differential traces, while analog and power-return paths should remain appropriately partitioned. Because the supplied search results do not expose complete electrical limit tables, pin mapping, package dimensions, or absolute maximum ratings, engineers should use the official NXP TJA1046 datasheet for final schematic and layout sign-off. This page consolidates the verified NXP product description, distributor package identification, official datasheet link, purchasing sources, and replacement-validation gaps. It also distinguishes confirmed dual 5 Mbps CAN functionality from unverified assumptions about voltage tolerances, loop delay, bus fault handling, and exact exposed-pad requirements.

TJA1046VTKZ

TJA1046VTKZ - Dual HS CAN Transceiver w/ Standby | NXP | Automotive

The NXP TJA1046VTKZ is a dual high-speed CAN transceiver housed in a 14-pin HVSON (3x4.5 mm) package with exposed pad, providing two independent interfaces between a CAN protocol controller and the physical two-wire CAN bus. Each channel is functionally equivalent to a TJA1044GT high-speed CAN transceiver, supporting HS-CAN data rates per ISO 11898-2/5 and ISO 11898-2:2016 in automotive networks. The device is VeLIO compliant and qualified for automotive body and powertrain networks. A CAN transceiver is a physical-layer (PHY) interface IC that translates the differential CANH/CANL bus voltages required for robust in-vehicle networking into standard digital TX/RX logic levels for a microcontroller's CAN protocol controller. It sits between the MCU's CAN module (data link layer) and the wired CAN bus, providing the dominant/recessive bit signaling, common-mode rejection, bus fault protection, and ESD handling required by ISO 11898. The TJA1046VTKZ integrates two such PHYs on one die, saving board area versus discrete single-channel transceivers in zonal and gateway ECUs. Key features of the TJA1046VTKZ include very low-current standby mode with bus wake-up (per ISO 11898-5), thermal protection, bus dominant time-out, and high ESD robustness on the bus pins. Both channels share the same standby/wake behavior; the device targets automotive ECUs requiring dual CAN channels such as body control modules, gateway ECUs, and ADAS sensor aggregation nodes. The HVSON-14 (3x4.5) exposed-pad package provides a low thermal resistance path, which is critical for under-hood and high-ambient-temperature installations. The architecture pairs two independent TJA1044-style transceivers on a common die, with shared thermal shutdown and independent TXD/RXD/standby control per channel. Each channel includes a low-drop voltage regulator for internal logic, slope control for reduced EMI, and an integrated bus termination concept suitable for HS-CAN nodes. Per the NXP datasheet the part is optimized for automotive EMC performance including SAE J2962-related conformance expectations. Typical applications include dual-CAN automotive ECUs (body control modules, gateways, instrument clusters), industrial CAN nodes with dual buses (CANopen, DeviceNet), and OBD-II dual-channel diagnostic interfaces. The standby mode makes it suited for always-on networks that must wake on bus activity. When designing with the TJA1046VTKZ, ensure the exposed pad is soldered to a sufficiently large copper pour (>= 50 mm^2) and that the bus stubs to CANH/CANL are kept below the ISO 11898-2 maximum length for the chosen data rate. A common-mode choke and split termination improve EMI/ESD margin.

TJA1048

TJA1048 - Dual High-Speed CAN Transceiver, SOIC-14 | NXP

The NXP Semiconductors TJA1048 is a dual high-speed Controller Area Network (CAN) transceiver with Standby mode that provides the physical interface between a CAN protocol controller and the differential two-wire CAN bus in automotive and industrial systems. Each of the two independent transceiver channels integrates a CAN protocol controller side (TXD/RXD) and a bus side (CANH/CANL) differential driver/receiver, supporting the ISO 11898-2:2016 high-speed CAN physical layer standard. The device is housed in a 14-pin SOIC package, with the TJA1048T,118 variant supplied on tape-and-reel for high-volume assembly. A high-speed CAN transceiver (HS-CAN transceiver) is the physical-layer interface IC that converts digital transmit/receive logic levels from a CAN controller (typically an MCU or SBC) into the differential dominant/recessive voltage signaling on a CAN bus, while also providing bus fault protection, ESD robustness, and low-power modes. The transceiver operates at the lowest tier of the OSI layered model, beneath the CAN data link layer (typically handled in the MCU's CAN controller). The TJA1048 belongs to NXP's third-generation HS-CAN family, offering improved electromagnetic compatibility (EMC) and quiescent-current performance compared with first-generation devices such as the TJA1040, while combining two complete transceivers into a single package to save board space on dual-bus automotive ECUs. Key features of the TJA1048 include very low quiescent current in Standby mode for battery-connected nodes, robust ±8 kV HBM ESD handling on the bus pins, bus terminal short-to-battery and short-to-ground protection, thermal shutdown, and a transmit-data (TXD) dominant-timeout function that prevents the bus from being permanently driven dominant by a stuck TXD pin. The split termination pin (STB/VIO reference) and the dedicated Standby control input allow the system MCU to selectively power down one or both channels when the bus is idle. The TJA1048 architecture places each transceiver channel as an independent differential line driver with slope-controlled output stages to limit electromagnetic emissions and meet automotive OEM EMC requirements. A common-mode stabilization circuit maintains bus symmetry across wide ground-offset conditions encountered in 12 V and 24 V vehicle networks, allowing reliable communication even during transient events such as engine cranking or load dump. Typical applications include automotive body-control modules, gateway ECUs that bridge CAN and CAN-FD buses, dual-channel infotainment network nodes, industrial CAN-IO modules with redundant bus interfaces, and OBD-II diagnostics adapters that monitor two independent CAN networks simultaneously. The device is qualified per AEC-Q100 and supports the operating temperature range required under the -40 C to +125 C automotive grade. When designing with the TJA1048, pay attention to bus termination: a 120 ohm split-termination network (60 ohm plus 60 ohm with a capacitor to ground) at each end of the bus is recommended to suppress common-mode emissions. The Standby pin transitions must respect the minimum bus-idle detection time before remote wake-up is acknowledged, otherwise the bus remains silent. According to NXP, unused channels should still have their TXD tied high (recessive) to avoid accidental bus dominance.

TJA1049

TJA1049 - High-Speed CAN Transceiver with Standby | NXP

The NXP TJA1049 is a third-generation high-speed Controller Area Network (CAN) transceiver that provides the physical interface between a CAN protocol controller and a two-wire differential CAN bus, supplied in an 8-pin SO (TJA1049T) or 8-pin HVSON (TJA1049TK) surface-mount package. The part supports the ISO 11898-2 high-speed CAN physical layer and offers improved ElectroMagnetic Compatibility (EMC) and Electrostatic Discharge (ESD) performance versus earlier TJA1040/TJA1050 generations, with a very low current standby mode and remote bus wake-up capability via CAN recessive-to-dominant detection. A CAN transceiver is the physical-layer silicon that converts the digital transmit/receive logic of a microcontroller's CAN protocol controller into the balanced differential voltage signaling required on the bus. The TJA1049 belongs to the high-speed CAN (ISO 11898-2) family, which sits hierarchically under the broader CAN protocol stack: physical layer transceiver -> CAN protocol controller -> higher-layer software (CANopen, J1939, AUTOSAR, etc.). It is the third-generation NXP HS-CAN transceiver, succeeding TJA1040 (first) and TJA1050 (second). Key features of the TJA1049 include: low-current standby mode with bus wake-up via CAN signaling; a Transmit Data (TXD) dominant-time-out to prevent bus lock-up if the controller fails; thermal shutdown protection; an SPLIT pin (HVSON variant) to stabilize the bus common-mode voltage when the network is not terminated; and ±8 kV HBM ESD protection on bus pins CANH and CANL (per IEC 61000-4-2). The supply voltage is 4.5 V to 5.5 V. Architecturally, the TJA1049 uses a low-dropout voltage regulator on VCC to power internal logic, a differential driver stage that sources/sinks bus current during dominant bits, and a differential receiver with high common-mode range for recessive bits. The standby current is typically below 15 µA, which is critical for automotive body controllers and ECUs that must wake on CAN activity without significant quiescent drain on the battery. Typical applications include automotive body-control modules, gateway ECUs between CAN and LIN or CAN-FD subnets, infotainment CAN interfaces, industrial CAN nodes requiring AEC-Q100-grade components, and OBD-II diagnostic interfaces. The very-low standby current also makes the device suitable for battery-powered nodes that wake on bus traffic. When designing with the TJA1049, observe the standby-state timing budget (typical wake-up filter time) when validating wake-up latency in your network stack. For the HVSON variant (TJA1049TK), the SPLIT pin requires a 10 nF to 47 nF capacitor to ground if used; if the SPLIT function is not needed, the pin can be left open per datasheet guidance.

TJA1049T/1Z - High-Speed CAN Transceiver with Standby | NXP

The NXP TJA1049T/1Z is a high-speed Controller Area Network (CAN) transceiver providing the physical interface between a CAN protocol controller and the two-wire CAN bus, housed in an 8-pin SOIC package. The TJA1049T variant is specified for 5V microcontroller supply rails, supports data rates up to 1 Mbit/s, and includes a low-current Standby mode with remote bus wake-up capability. The device implements the ISO 11898-2:2003 and ISO 11898-5:2007 physical layer standards and is qualified for the pending updated ISO 11898-2:2016 release. A CAN transceiver is a physical-layer interface IC that translates the digital transmit/receive signals of a CAN protocol controller into the differential voltage levels (CANH/CANL) defined by ISO 11898-2 on the bus, while also providing bus-side ESD protection and dominant/recessive arbitration. As an interface IC the TJA1049T/1Z sits between application-layer MCU/processor and the physical CAN bus, making it a foundational building block for in-vehicle networking, industrial automation and any system requiring robust differential serial communication. Key features include a very low quiescent current in Standby mode for battery-powered nodes, a SPLIT output for stabilizing the recessive common-mode voltage in networks with multiple unpowered nodes, and transmit data (TXD) dominant time-out protection that prevents the bus from being permanently clamped if the controller fails. The integrated bus wake-up filter rejects transients on CANH/CANL to ensure false wake-ups do not discharge the battery in automotive quiescent scenarios. Typical applications include automotive body and chassis ECUs, CAN-based powertrain nodes, industrial CANopen and DeviceNet modules, and any 5V microcontroller host that requires a compact, low-power standby-enabled physical-layer interface. Designers often pair the TJA1049T/1Z with 5V MCUs such as the NXP S12K or ST STM32 families, plus a 5V LDO and common-mode choke for EMI hardening. When designing with this part, observe the bus termination: 120 ohm resistors at each network end with optional split termination for better EMC performance. Decouple VCC with 100 nF ceramic close to the pin and provide a robust PCB ground return for the bus ESD clamps to operate as specified.

The CAN controller generates and interprets CAN frames, while the transceiver converts those digital signals into robust differential bus levels and converts received bus levels back into logic-compatible signals. In the hierarchy of electronic components, the TJA1049T/3J belongs to the CAN interface and physical-layer transceiver class, within interface ICs and networking semiconductors. The principal verified features include a 3 V to 5 V microcontroller-interface range, high-speed CAN operation, differential transmit and receive capability, standby support, and compatibility with the CAN physical layer standards listed by NXP. Its standby function is intended for systems that need low-current operation while retaining bus wake-up capability. The physical two-wire interface supports integration into automotive and industrial CAN networks while leaving arbitration, framing, error management, and message scheduling to the CAN controller. Technical use requires a CAN controller with TXD and RXD signal connections, a suitable transceiver supply, CAN bus termination, common-mode support, and correctly configured logic levels. The standby pin and mode timing should be reviewed against the system power-management strategy because entering or leaving standby can affect node availability. Because the verified excerpt does not provide a complete timing table, absolute transceiver delay, loop-delay, propagation-delay, receiver threshold, bus-fault, and current-limit values are left as data-needed fields rather than inferred. Typical applications include automotive body and powertrain electronics, industrial automation equipment, transport systems, embedded gateways, motor controllers, sensor networks, and CAN-based diagnostic equipment. The 8-pin SOIC package is useful when a through-hole-compatible surface-mount assembly process and a compact two-wire bus interface are required. For robust PCB implementation, place the transceiver close to the connector and CAN bus routing, provide solid ground-plane continuity, route CANH and CANL as a tight differential pair, and place termination only at the physical ends of the bus. Verify that the selected CAN controller, supply voltage, transceiver mode pins, and termination strategy match the complete manufacturer datasheet before production release. This page consolidates verified NXP product information, distributor references, package details, interface standards, application context, and design guidance. Missing electrical timing, current, environmental, and absolute maximum values are explicitly marked where the supplied verified data does not support a trustworthy value.

It interfaces a Controller Area Network protocol controller with a physical two-wire CAN bus and includes standby support for low-power operation. According to the NXP datasheet, the device is designed for automotive high-speed CAN applications. A CAN transceiver is an interface IC that converts logic-level controller signals into differential bus voltages and converts received differential bus levels into logic-compatible receive signals. In the system hierarchy, the TJA1049TKJ belongs to the CAN physical-layer transceiver class, connecting a CAN controller or microcontroller to the CANbus network while providing differential transmit and receive capability. The verified specifications identify a 1/1 driver and receiver arrangement, half duplex operation, 5 Mbps maximum data rate, and 300 mV receiver hysteresis. Its 4.75 V to 5.25 V operating supply range supports regulated 5 V automotive and embedded CAN systems. The standby function can reduce activity when the node is not required to communicate, while the small 8-HVSON package supports compact automotive electronics designs. The TJA1049TKJ is positioned for in-vehicle networks, diagnostic interfaces, body electronics, gateway modules, and industrial or embedded systems using high-speed CAN. It is suitable where a controller requires a physical-layer transceiver rather than a complete CAN controller. System designers must still provide appropriate bus termination, common-mode protection, decoupling, and PCB routing for the installed network topology. The package and pin configuration require careful attention to exposed-pad soldering and thermal behavior. Because the verified source data does not provide a detailed pin-by-pin public pinout, the pinout field is marked unavailable rather than reconstructed from memory. Application selection should also confirm the exact NXP ordering variant, package, and exposed-pad land pattern before PCB release. This page combines the verified manufacturer and distributor references with package-level engineering guidance, comparison fields, and application context for engineers evaluating the TJA1049TKJ.

TJA1050

TJA1050 - High-Speed CAN Transceiver, 5V | NXP Semiconductors

The NXP TJA1050 is a high-speed Controller Area Network (CAN) transceiver that provides the physical interface between a CAN protocol controller and the physical CAN bus, supporting data rates up to 1 Mbit/s in a standard 8-pin SO (SOIC-8) package. Designed for 5V supply operation, the TJA1050 delivers excellent electromagnetic compatibility (EMC) performance and very low power consumption, making it well-suited for both industrial and automotive applications. A CAN transceiver is an interface IC that sits between a microcontroller's CAN protocol controller and the differential CANH/CANL bus wires. Its hierarchical role is: CAN transceiver → bus interface IC → interface integrated circuit → semiconductor. The TJA1050 family forms part of NXP's third-generation high-speed CAN transceivers, succeeding earlier devices like the PCA82C250 with improved slope control, lower electromagnetic emissions, and integrated protection features against bus shorts and transient voltages. Key features include an operating supply voltage range of 4.75V to 5.25V, low quiescent current consumption, integrated thermal protection, and a recessive bus output voltage that approximates the supply voltage (VCC) for improved logic-level compatibility. The device supports both normal and silent (standby-like) modes selected via the S pin and provides differential transmit/receive capability across an extended common-mode range on the bus. Differential receiver thresholds are tightly controlled to support CAN-FD-ready bit timing in many classic CAN networks. The architecture uses a current-driven recessive output and a dominant-driving topology with slope control to minimize ringing and RF emissions. An internal watchdog and thermal shutdown safeguard the die against bus shorts to battery or ground, while an undervoltage detection circuit disables the transmitter when VCC drops below the operational threshold to prevent erroneous bus states during power-up or power-down sequences. Typical applications include automotive body control modules, industrial CAN-based sensor networks, building automation gateways, and battery management systems where galvanic isolation can be implemented with a transformer or capacitive barrier after the transceiver stage. The TJA1050 is commonly paired with 8-bit or 32-bit microcontrollers that include an integrated CAN controller, such as NXP's LPC and S32K families. When designing with the TJA1050, place a 120 Ω termination resistor at each end of the CAN bus segment and keep the stub length under roughly 30 cm at 1 Mbit/s. Decouple VCC with a 100 nF ceramic capacitor close to the supply pin, and provide adequate ground plane coverage under the bus traces to maintain the differential impedance target of 120 Ω.

TJA1050T/CM - 1Mbit/s CAN Transceiver | NXP | SOIC-8

The NXP Semiconductors TJA1050T/CM is a 1/1 high-speed CAN transceiver with a 4.75 V to 5.25 V supply range, data rates up to 1 Mbit/s, and an 8-pin SOIC package. It provides the physical-layer interface between a CAN protocol controller and a two-wire differential CAN bus. The device supports differential transmission and reception for automotive and industrial networks. A CAN transceiver is an interface IC that converts logic-level controller signals into differential bus signals and converts received bus levels back into digital receive data. In system terms, the TJA1050T/CM belongs to the CAN physical-layer transceiver class, interface IC category, and broader semiconductor hierarchy. Its differential signaling supports noise-resistant communication over long cables and through electrically noisy environments. The verified device data identifies ISO 11898 compatibility, operation up to 1 Mbaud, low electromagnetic emission, a differential receiver with a wide common-mode range, and high electromagnetic immunity. An unpowered node does not disturb the bus lines, while bus-pin protection helps improve robustness. The TXD dominant timeout prevents a permanently dominant transmitter state if TXD is held low by a controller or system failure. The TJA1050T/CM is suitable for CAN-based automotive electronics, industrial control systems, embedded equipment, and communications infrastructure. The NXP product page describes its use between a CAN protocol controller and a two-wire CAN bus. Its 5 V supply requirement makes controller-interface compatibility especially relevant for legacy systems designed around 5 V logic. PCB implementation requires careful termination and bus routing. CAN-H and CAN-L should be treated as a differential pair, with a 120 ohm termination installed at each end of the main bus. The supply should be decoupled close to the device, and the transceiver should be positioned to minimize exposed high-current bus traces. The product page marks the TJA1050 as end of life, so engineers should treat availability and lifecycle migration as important design constraints. The TJA1050T/CM is therefore most appropriate for maintaining or repairing existing 5 V CAN designs, while new designs should confirm the NXP migration path and validate pin, electrical, and protocol compatibility before release. This page combines manufacturer lifecycle information, distributor product identifiers, verified CAN features, and practical interface guidance for engineers evaluating TJA1050T/CM procurement, replacement, PCB reuse, and legacy-system support.

The NXP TJA1051T/1J is a 5 Mbit/s high-speed CAN transceiver with 5 V operation, differential transmit and receive capability, and an 8-pin SOIC package. It interfaces a CAN protocol controller to a physical two-wire CAN bus and is associated with automotive applications. The device is also described as normal-mode, SILENT-mode-capable and AEC-Q100 qualified in the supplied component data. A CAN transceiver is the physical-layer interface between a microcontroller or dedicated CAN controller and the CAN bus. The controller generates and interprets logic-level CAN TX and RX signals, while the transceiver converts those signals into the differential CANH and CANL bus signals. A high-speed CAN physical layer supports differential signaling, noise rejection and reliable communication over twisted-pair wiring. The TJA1051T family is positioned for high-speed CAN networks at data rates up to 5 Mbit/s. The verified component listing identifies a nominal 5 V supply, normal/silent operation, 8-pin SO packaging and tape-and-reel ordering for TJA1051T/1J. NXP also states that TJA1051T is backward compatible with the TJA1050, which is important when upgrading an existing CAN interface. The TJA1051 provides separate transmit-dominant, silent and receive behavior for bus management. Silent mode can be useful when a node must monitor or receive without driving the bus, although network software must coordinate this state with other nodes to avoid hidden transmitter conflicts. The device should be paired with an appropriate CAN controller, bus termination, common-mode protection and a correctly decoupled 5 V supply. Typical installations include automotive body, powertrain-adjacent, gateway and diagnostic networks; industrial automation equipment; elevator and building-control systems; and embedded CAN gateways. The 5 Mbit/s capability suits short, well-terminated, high-quality CAN networks where maximum latency is more important than long cable distance. In every case, PCB layout, grounding and bus protection remain critical. For layout, place the transceiver close to the bus connector, provide a continuous ground reference, route CANH and CANL as a coupled pair, and place termination only at the physical ends of the bus. Avoid long stubs between the transceiver and connector. Power filtering and common-mode chokes may be needed when the cable leaves the controlled PCB environment.

NXP Semiconductors TJA1051T/2Z is a 5 Mbit/s high-speed CAN transceiver with Silent Mode, packaged in an 8-pin SOIC for interface bridging between a CAN protocol controller and a physical two-wire CAN bus. The verified distributor listing identifies the /2 ordering option as a Silent-Mode variant, while the manufacturer document covers the TJA1051T family and its compatibility with TJA1050. Its differential transmit and receive arrangement supports automotive and industrial Controller Area Network nodes. A CAN transceiver is the physical-layer interface within a Controller Area Network. It converts controller TXD and error-indicator signals into differential bus output, then converts differential bus levels into RXD data for the protocol controller. This device sits between digital microcontroller I/O and the CAN_H and CAN_L network conductors, combining bus-driver, receiver, and control functions in one IC. The TJA1051T/2Z headline characteristics are a maximum listed data rate of 5 Mbit/s and an 8-pin SOIC package. Silent Mode provides an operating state identified by the verified product listing, but the supplied excerpts do not quantify its input, output, or supply current. The manufacturer also states that the TJA1051T is backward compatible with the TJA1050, which is important when upgrading an existing CAN node without changing its controller-facing interface. The TJA1051 family targets high-speed CAN networks, including automotive systems, where robust differential signaling and transceiver integration simplify node construction. Differential bus operation rejects common-mode noise better than a single-ended interface when the network, termination, grounding, and connector implementation are correctly designed. This makes the part suitable for vehicle body electronics, industrial automation equipment, embedded controllers, and CAN-based sensors. The primary design consideration is preserving compatibility at both the software and physical layers. A replacement must match the SOIC-8 footprint, pin functions, supply expectations, bus timing, and controller logic. Bus termination, common-mode range, loop delay, recessive/dominant behavior, and maximum cable length must be checked against the complete network design rather than inferred solely from the 5 Mbit/s headline rate. For sourcing and engineering context, this page combines the exact verified distributor identity, manufacturer datasheet link, availability claims, family-level compatibility information, and practical design guidance. It separates verified facts from unspecified electrical details so procurement teams can review TJA1051T/2Z without relying on unverified substitutions.

The NXP TJA1052IT is a galvanically isolated high-speed CAN transceiver that provides a robust interface between a CAN protocol controller and the physical two-wire CAN bus, housed in a 16-pin SO package and specifically targeted at Electric Vehicle (EV) and Hybrid Electric Vehicle (HEV) applications. An isolated CAN transceiver is a specialized interface IC that combines a high-speed CAN physical layer with on-chip galvanic isolation, typically using integrated coreless transformer or silicon-dioxide (SiO2) dielectric barriers to withstand high common-mode transients in automotive high-voltage environments. Within the broader semiconductor taxonomy, the TJA1052IT sits in the hierarchy isolated CAN transceiver -> CAN transceiver -> CAN interface IC -> automotive interface IC -> power management & signaling semiconductor. Isolation eliminates ground loops between the low-voltage domain (MCU/host) and the high-voltage CAN bus, which is essential when the ECU and chassis sit at different potentials. Key specifications include integrated galvanic isolation rated to withstand high common-mode voltages, support for CAN data rates up to 1 Mbit/s per ISO 11898-2, a wide supply range on the bus side, and very low loop delay suitable for time-triggered CAN (CAN FD-ready) networks. The 16-pin SO package exposes dedicated pins for VCC (logic-side supply), VBUS (bus-side supply), TXD, RXD, CANH, CANL, and the integrated isolation barrier. Architecturally, the TJA1052IT integrates a digital isolator and a CAN transceiver die, with the isolation barrier providing reinforced insulation. This monolithic approach reduces PCB area versus a discrete transceiver + digital isolator solution and improves reliability by eliminating intermediate interconnects. Typical applications include EV/HEV battery management systems, on-board chargers (OBC), DC fast-charging communication links (ISO 15118 PLC not included), traction inverter CAN nodes, and industrial CAN networks requiring reinforced isolation. When designing with the TJA1052IT, place decoupling capacitors close to both VCC and VBUS pins and respect the creepage/clearance rules on the PCB around pins straddling the isolation domain. The device is drop-in compatible with the TI ISO1042 in 16-SO footprint, simplifying second-source strategies.

TJA1052IT-1Y

TJA1052IT-1Y - Galvanically Isolated HS CAN Transceiver | NXP

The NXP Semiconductors TJA1052IT-1Y is a galvanically isolated high-speed CAN (Controller Area Network) transceiver housed in a 16-pin Small Outline (SO-16) package. It provides an isolated interface between a CAN protocol controller and the physical two-wire differential CAN bus, integrating on-chip galvanic isolation that traditionally required a separate digital isolator plus a CAN transceiver. The part is specifically targeted at Electric Vehicles (EV) and Hybrid Electric Vehicles (HEV), where robust isolation between high-voltage traction domains and low-voltage ECU communication is mandatory. A CAN transceiver is the physical-layer bridge inside an in-vehicle network: it converts the differential logic-level signals from a CAN controller (TXD, RXD) into the bus-side differential voltage on the CANH and CANL lines that meet ISO 11898-2/-5, while protecting the host controller from bus-level transients. The TJA1052i family adds integrated digital isolation (typically using on-chip coreless transformer technology) to that bridge, replacing a two-chip solution (isolator + transceiver) with a single component and simplifying PCB layout while improving common-mode transient immunity (CMTI) in motor-drive environments. Key features include ISO 11898-2/-5 compliant high-speed CAN data rates up to 1 Mbit/s, integrated galvanic isolation rated for 1 kV (digital isolator channel rating per the part classification), tight loop delay for time-triggered CAN (TTCAN) operation, and integrated bus-side protection for harsh automotive electrical environments. The TJA1052i is designed to operate over the full automotive temperature range and supports low-power standby modes for battery-friendly quiescent current draw when the bus is silent. The architecture uses NXP's high-speed CAN transceiver core combined with on-chip galvanic isolation cells, removing the need for external optocouplers or digital isolator ICs while providing the same reinforced isolation barrier between the CAN controller domain and the bus domain. This two-domain split is essential in EV/HEV powertrain ECUs where the bus may sit on a high-voltage referenced plane. Typical applications include EV and HEV battery management system (BMS) CAN nodes, onboard chargers, DC-DC converter telemetry, electric power steering (EPS) communication links, and industrial CAN-isolated gateways that must bridge different ground domains. Designers use the TJA1052IT-1Y where ISO 11898 bus timing must be preserved across an isolation barrier without adding a discrete isolator stage. A key design consideration is that the bus-side and logic-side grounds must remain galvanically separate; do not bypass the isolation by shorting the two ground planes. Also confirm the 1 kV channel rating meets the end-application's reinforced or basic isolation requirement before reuse in higher-voltage systems.

It targets Electric Vehicles (EV), Hybrid Electric Vehicles (HEV), and any application requiring reinforced isolation between bus nodes. The integrated digital isolator and CAN transceiver in one package eliminates the need for a discrete isolator plus discrete transceiver, cutting board area roughly in half and simplifying EMC design. A CAN transceiver is a physical-layer (PHY) device that converts differential CAN logic levels from a microcontroller's CAN controller into the dominant/recessive bus signaling required by ISO 11898-2, while providing bus-side fault protection and EMC robustness. The TJA1052IT specifically adds on-chip galvanic isolation - replacing a two-chip solution (isolator + CAN transceiver) with a single device - and is part of the broader hierarchy: CAN transceiver -> interface IC -> integrated circuit. Key features include data rates up to 5 Mbps (CAN FD capable), an isolation voltage of 5000 V RMS for 1 minute per UL 1577, bus fault protection from -27V to +40V, an operating supply range that supports both 1.8V/3.3V/5V MCU sides, and AEC-Q100 qualification for automotive environments. A low-power standby mode with bus wake-up detection is also present, achieved through a dedicated STBY pin and a remote wake-up pattern recognizer compliant with ISO 11898-5. The TJA1052IT uses NXP's integrated capacitive-coupled isolation technology plus a proven CAN PHY, achieving low loop delay under 200 ns - critical for CAN FD frames at the maximum payload phase. Compared with discrete optocoupler + CAN transceiver solutions, the integrated approach reduces propagation delay variation over temperature by a factor of 2-3, improving timing margin in large or noisy automotive networks. Typical applications include EV/HEV battery management system (BMS) bus isolation, OBC (on-board charger) to VCU communication, industrial CAN bus nodes requiring 5 kV isolation (solar inverters, motor drives), EV charging stations with isolated CAN, isolated industrial sensor hubs, and automotive ECU-to-ECU isolation. A key design consideration is the supply topology: the device has two VCC rails - VCC1 (logic/microcontroller side, 2.5V-5.5V) and VCC2 (bus-side, 4.5V-5.5V) - each requiring local decoupling. Designers should follow NXP application note AN11253 for PCB layout, especially maintaining a creepage/clearance margin under the isolation barrier.

The device operates from a 3 V to 5.25 V supply on the logic/microcontroller side and supports a CAN data rate of up to 5 Mbps, making it suitable for Classic CAN and CAN FD frame formats. The integrated isolation removes the need for an external digital isolator + isolated DC-DC combination in many designs, reducing BOM count and PCB area. What is an isolated CAN transceiver? A CAN transceiver is the physical-layer bridge between a CAN controller (typically embedded in a microcontroller) and the differential CAN bus lines (CANH/CANL). A galvanically isolated version inserts a high-voltage barrier - here implemented via on-chip capacitive coupling - between the logic domain and the bus domain, breaking ground loops and protecting low-voltage MCU I/O from high-voltage transients common in automotive 12 V/24 V powertrain systems and industrial installations. Key features of the TJA1052IT/2Y include 1/1 unidirectional channel count, 2.5 kVrms isolation voltage rating, 5 Mbps maximum data rate, a standby mode for low quiescent current, and compatibility with 1.8 V and 3.3 V controller logic via separate VIO/VCC rails.

The device connects a CAN protocol controller to the physical CANH and CANL bus conductors while providing differential transmit, receive, and fault-tolerance functions. A CAN transceiver is the physical-layer interface between a digital CAN controller and the wired CAN network. The TJA1055 family belongs to the interface-IC hierarchy and is specifically optimized for in-car low-speed communication, where its 125 kBd target complements higher-speed CAN controller and transceiver families. Its enhanced fault tolerance helps maintain operation when the bus is shorted to ground, shorted to the supply, or open-circuit, subject to the detailed protection and operating conditions stated by NXP. Key verified characteristics include a 125 kBd low-speed CAN application target, a 4.75 V minimum supply, a 5.25 V maximum supply, and a 14-pin SOIC package. NXP identifies the TJA1055 as pin-to-pin compatible with the TJA1054 and TJA1054A. Distributor listings also identify TJA1055T/1J as an automotive CAN interface available in tape-and-reel ordering. The transceiver should be placed near the CAN bus connector, with its CANH and CANL pins connected to the protected bus wiring and its TXD and RXD pins connected to the CAN controller. Because the device is intended for passenger-car and other low-speed CAN links, system designers should verify timing, termination, bus topology, logic levels, and protection requirements against the manufacturer datasheet before production release. The TJA1055T/1J is suitable for automotive body electronics, comfort modules, diagnostic equipment, sensor nodes, and other 125 kBd CAN applications. Its principal design consideration is that CAN bus behavior depends on termination, wiring, common-mode conditions, and transceiver protection. A CAN bus should not be treated as a generic communication line; the selected transceiver, controller, and network implementation must be validated together.

It supports data rates up to 5 Mbps (CAN FD capable), operates over a wide supply range of 4.75 V to 5.25 V, and is designed for high-speed CAN applications in the automotive industry. A CAN transceiver (also called a CAN bus driver/receiver) is a physical-layer IC that converts the differential digital signaling of a CAN protocol controller into the differential voltage levels required by the ISO 11898-2 CAN bus standard. It sits between a microcontroller's CAN module and the bus wires (CANH/CANL), providing immunity to common-mode noise and ESD protection. CAN transceivers belong to the broader family of interface ICs and are essential building blocks for in-vehicle networking, industrial automation, and any distributed control system that uses the CAN protocol. The TJA1057BTK delivers differential transmit capability to the bus with controlled slew rate, and differential receive capability with high common-mode rejection. It supports both Normal and Silent operating modes, where Silent mode disables the transmitter for listen-only diagnostics. The device is optimized for low electromagnetic emission (EME) and high electromagnetic immunity (EMI), meeting the stringent automotive requirements for CAN bus communication. Integrated thermal protection, bus dominant time-out, and under-voltage detection on VCC enhance system reliability. The 8-pin HVSON package (3x3 mm) with exposed thermal pad offers a very compact footprint suitable for space-constrained ECUs (Electronic Control Units). The exposed pad provides a low thermal resistance path to the PCB copper, allowing the IC to handle the bus fault conditions specified in ISO 11898-5 without derating. The TJA1057BTK is functionally identical to the TJA1057CT within the SOI3+ process family - they differ only in the VIO supply pin logic level handling. Typical applications include automotive body and comfort ECUs, infotainment CAN interfaces, industrial CAN nodes, building automation, and any embedded system requiring a robust, standardized CAN physical layer. In these use cases, the TJA1057BTK acts as the bus interface between a 3.3 V or 5 V microcontroller's CAN controller and the 12 V automotive CAN bus. A key design consideration is the bus termination: a 120 Ω resistor (or split 60 Ω + 60 Ω with capacitor) must be present at each end of the CAN bus segment. The HVSON exposed pad must be soldered to a copper pad of at least 1 mm² to ensure proper thermal performance under continuous bus fault conditions.

Housed in an 8-pin HVSON (3x3 mm) package with exposed pad, it supports data rates up to 5 Mbps and is qualified to AEC-Q100 Grade 1 for automotive applications. A CAN transceiver (also called a CAN bus transceiver or CAN interface IC) is a physical-layer device that converts the digital transmit/receive logic signals of a CAN protocol controller inside a microcontroller into the differential CANH/CANL bus signals required on the actual network. CAN belongs to the broader category of serial communication interface ICs, alongside RS-485, RS-232 and LIN transceivers. The TJA1057 family specifically targets high-speed classical CAN and CAN FD (Flexible Data-rate) networks used for powertrain, chassis and body electronics. Key features include a low electromagnetic emission (EME) common-mode choke design, high electromagnetic immunity (EMS), a low-power Standby mode with remote wake-up capability, and ±8 kV HBM ESD protection on the bus pins (per IEC 61000-4-2 on the bus pins, per datasheet). The transceiver operates from a 4.5 V to 5.5 V VCC supply, supports bus voltages from -27 V to +40 V, and provides a TxD dominant time-out for fail-safe behavior. The TJA1057BTK/0J variant carries the 'B' suffix (VIO supply pin present, allowing direct level-shifting to MCUs at 3.3 V or 5 V) and the 'TK' suffix indicating the 8-pin HVSON package with exposed pad. The /0J suffix designates the production ordering code (tape-and-reel packaging). Internally, the device uses a silicon-on-insulator (SOI) process (NXP SOI3+ family), which gives it excellent ESD and latch-up immunity versus older bulk-silicon CAN transceivers like the TJA1050. Typical applications include automotive body control modules (BCMs), gateway ECUs, instrument clusters, HVAC control units, transmission ECUs and industrial CAN nodes operating up to 1 Mbit/s in classical CAN or 5 Mbps in CAN FD networks. The transceiver interfaces directly to NXP S32K and most third-party automotive MCUs. When designing with this part, place the VCC decoupling capacitor (typically 100 nF) directly adjacent to pin 8 and connect the exposed pad (pin 0) to a large PCB ground plane for thermal dissipation and low-impedance return paths. Match the CANH/CANL bus termination to 120 Ω at the network ends to satisfy ISO 11898-2 and avoid signal-integrity issues at high bus loads.
