The Infineon TLE8250G is a high-speed CAN transceiver with one transmitter and one receiver, data rates up to 1 Mbit/s, and ISO 11898-2 compliance in an eight-pin PG-DSO-8 surface-mount package. It serves as the physical-layer interface between a CAN protocol controller and a two-wire differential CAN bus. According to the Infineon product page and manufacturer datasheet, the device is designed for automotive and industrial networks, with low electromagnetic emissions and emissions-related interference, high electromagnetic immunity, and robust ESD protection. A CAN transceiver is a network interface IC within the broader communications-semiconductor hierarchy. It converts logic-level TXD and RXD signals into the differential CANH and CANL bus signals, then converts received bus levels back into a controller-compatible RXD signal. High-speed CAN is a two-wire differential network designed for robust, priority-based communication between electronic control units, where common-mode rejection and disturbance tolerance are central to reliable operation. The TLE8250G combines a 1 Mbit/s-capable CAN driver with a receiver interface and bus protection functions. Its symmetric CANH and CANL behavior supports low EMI in applications where electronic modules must coexist on a shared harness. The device supports partially supplied networks, an important characteristic for automotive systems where some nodes can be unpowered while others remain active. In power-down mode, receiver input resistors are switched off so the transceiver input becomes highly resistive, reducing unwanted loading of an inactive bus. Infineon Smart Power Technology combines bipolar and CMOS control circuitry with DMOS power devices on one monolithic circuit. The manufacturer describes this technology as supporting high ESD robustness and high electromagnetic immunity. The TLE8250G and its Smart Power Technology are stated to be AEC qualified. The transceiver also meets or exceeds ISO 11898-2 requirements and is offered in a RoHS-compliant PG-DSO-8 package, making it appropriate for electronic control units, body modules, gateways, sensors, and industrial automation interfaces. Use the TLE8250G when the PCB already expects an eight-pin PG-DSO-8 CAN interface and the bus operates at or below 1 Mbit/s. Designers should confirm the transceiver I/O voltage against their controller, preserve the CAN bus termination network, and follow the manufacturer’s layout guidance to minimize radiated emissions. Because only verified electrical limits, supply ranges, temperature ranges, and pin-level details are not included in the supplied search data, those values require confirmation in the manufacturer datasheet before release to production. The TLE8250G is also fully pin- and function-compatible with its Infineon predecessor, the TLE6250G, according to the verified manufacturer documentation. This predecessor relationship provides a documented upgrade path, but design reviews should still compare operating voltages, timing, transient immunity, and lifecycle requirements for the exact production variant. This page synthesizes manufacturer specifications, compatibility information, application guidance, and sourcing references that are not presented together on a distributor search page.

The LIN bus connection also needs careful review of transceiver placement, trace geometry, grounding, and protection strategy so that switching events and external wiring do not degrade communication reliability. This product page organizes the confirmed device functions, automotive interface role, package information, and engineering use cases into one reference. It also distinguishes verified drop-in replacements from functional alternatives so that PCB reuse decisions are based on package, pin, and parameter compatibility rather than only on the shared LIN interface category.

It supplies a microcontroller and associated peripherals with up to 70 mA while providing the physical-layer interface for LIN bus communication. A LIN transceiver, also called a LIN interface or LIN physical-layer device, connects a low-speed serial network controller to a vehicle communication bus. In the broader hierarchy, it belongs to the LIN interface transceiver class, interface IC category, and automotive semiconductor ecosystem. Integrating the voltage regulator with the bus interface reduces the number of external power components needed in compact automotive modules while preserving a stable 5 V supply for the local controller and peripherals. The TLE8457CSJ family combines a LIN transmitter, LIN receiver, and low-dropout regulator in one integrated circuit. Its 20 kbit/s LIN data rate suits body electronics and comfort systems, while the 70 mA regulator output is intended for local microcontroller support rather than high-current loads. A low standby current of 20 µA is specified for the device family, helping reduce quiescent consumption when an automotive module enters a low-power state. The PG-DSO-8 package is designed for surface-mount assembly and is associated with an automotive qualification grade of AEC-Q100. The device is identified with a one-transmitter, one-receiver configuration, and its RoHS 3 compliant and REACH unaffected declarations support use in modern automotive electronics supply chains. Moisture sensitivity is listed as MSL 3 for 168 hours, making controlled handling and reflow-profile management important during manufacturing. Typical uses include LIN-controlled door modules, seat and climate-control electronics, body-control interfaces, sensor nodes, and compact automotive peripheral units. In each case, the transceiver handles the physical bus levels while the integrated 5 V regulator powers the local processing circuitry. Designers should also check the LIN bus topology, termination, transceiver enable behavior, wake-up requirements, and available regulator current before assigning a supply load to the internal LDO. For a new PCB, follow the manufacturer pin-description table for signal assignment and place the input, output, and bus-decoupling components close to their associated pins. Keep the LIN bus routing away from sensitive analog and high-speed digital paths, and confirm that the chosen connector, ESD strategy, and grounding arrangement preserve the integrity of the physical layer. This page consolidates the verified electrical ratings, package information, automotive compliance details, procurement workflow, and engineering guidance needed to evaluate the TLE8457CSJXUMA1 for a LIN-connected automotive module.
TLE8457DLEXUMA1 - 3.3V LIN Transceiver | Infineon
Infineon Technologies TLE8457DLEXUMA1 is a single-channel LIN transceiver with an integrated 3.3 V voltage regulator, 20 kBd LIN communication, and an integrated 70 mA supply for a microcontroller and peripherals. The device is packaged in an 8-pin PG-TDSON-8-1 automotive surface-mount package and is identified as AEC-Q100 qualified. Its LIN interface supports bidirectional communication compliant with LIN specification 2.2A and SAE J2602. A LIN transceiver, also called a Local Interconnect Network transceiver, connects a low-cost microcontroller to a vehicle network that uses one signal wire. The communication architecture is based on a master node and one or more slave nodes. Because LIN is designed for slow, short-range vehicle sub-networks, its physical-layer transceiver combines a regulated supply, bus interface, logic-level data interface, and fault-recovery functions in one device. The TLE8457DLEXUMA1 uses a stable 3.3 V regulator to supply a microcontroller and attached peripherals up to 70 mA. This integration can reduce the number of discrete supply components and simplify PCB allocation in compact body, comfort, or sensor nodes. The 20 kBd bus rate is suitable for LIN 2.2A applications in which nodes exchange diagnostic or control information over low-speed vehicle networks. The LIN physical layer provides bidirectional communication and is compliant with LIN specification 2.2A and SAE J2602. Its integrated regulator includes undervoltage-reset protection for the supplied microcontroller and peripherals. Exact input-voltage limits, regulator dropout behavior, bus thresholds, protection details, and timing limits should be taken directly from the Infineon TLE8457C/TLE8457D manufacturer datasheet when designing the power and interface networks. Typical uses include LIN gateway modules, door and window control units, seat-control modules, climate-control peripherals, ambient-light sensors, and other distributed vehicle nodes. The integrated 3.3 V supply is particularly useful when the host controller and its immediate peripherals operate from a common low-voltage rail while also communicating through the LIN bus. Layout the LIN bus connection for automotive transient immunity, keep the transceiver close to its connector, and provide the decoupling and protection network recommended by the manufacturer. Confirm the package land pattern and exposed-pad thermal requirements against the PG-TDSON-8-1 drawing before release because exposed-pad soldering and copper treatment strongly affect assembly yield and thermal performance. This product page organizes the manufacturer specifications, interface requirements, application context, and design constraints for engineers evaluating the TLE8457DLEXUMA1. It also distinguishes verified drop-in alternatives from merely similar automotive LIN devices, helping prevent footprint or function mismatches during replacement planning.
TLE8458GXUMA1 - Integrated 5V LIN Transceiver | Infineon
The Infineon TLE8458GXUMA1 is an automotive LIN transceiver with an integrated low-dropout 5 V voltage regulator, combining a 1/1 LIN bus interface and a single fixed-output regulator in an 8-pin DSO surface-mount package. The device is intended to supply a LIN-connected microcontroller while operating a LIN bus from the same automotive power architecture. A LIN transceiver is a physical-layer interface IC for the LIN bus, a low-cost single-wire automotive communication network. Its hierarchy runs from LIN transceiver to vehicle-network transceiver, automotive interface IC, and power-management semiconductor. Integrating the regulator eliminates a separate 5 V supply circuit for compatible microcontroller domains and reduces PCB area, component count, and the number of power-supply interconnects. Verified distributor data identifies the TLE8458GXUMA1 as a fixed positive, single-output LDO regulator with a minimum input voltage of 5.5 V, 2% maximum voltage tolerance, eight gull-wing terminals, and a 10.4 kBd LIN interface rate. The same 5.5 V minimum input condition permits the regulator and LIN transceiver to operate from a common automotive supply while providing a regulated 5 V rail to the attached microcontroller. The LIN side provides one driver and one receiver for a typical LIN master or slave node. It supports nodes requiring combined communication and regulated supply, such as door modules, body controllers, seat controllers, climate-control panels, lighting modules, and compact automotive sensor nodes. Because LIN uses a single-wire bus, the interface reduces wiring cost compared with a multiwire automotive network while retaining a defined physical-layer interface for distributed vehicle electronics. The 8-pin DSO package is surface mount and compact, but the exposed environmental requirements of automotive electronics make PCB planning important. Route the LIN connection away from sensitive analog and communication nodes, keep the regulator output close to its decoupling capacitor, and use a return path that avoids high-current switching currents. Verify absolute maximum voltages, output load conditions, bus termination strategy, and supply transient behavior against the manufacturer datasheet before releasing a production design. Pricing, exact absolute maximum ratings, temperature limits, output-current capability, and a complete pin map were not supplied in the verified data and therefore remain marked as data needed rather than inferred. This page consolidates distributor identification, the TLE8458G family relationship, pin-compatible stand-alone LIN-transceiver context, and practical application guidance beyond a distributor catalog listing.

A FlexRay transceiver is a physical-layer (PHY) device that sits between a microcontroller's FlexRay Communication Controller and the differential FlexRay bus. It converts digital logic-level signals from the controller into differential bus voltages conforming to the FlexRay electrical specification, and vice versa for reception. The transceiver category sits within the broader automotive communication IC hierarchy of transceivers -> interface ICs -> integrated circuits. FlexRay was developed as a deterministic, fault-tolerant backbone for high-speed in-vehicle networking, supporting time-triggered and event-triggered communication with bandwidth up to 10 Mbit/s per channel. Key features of the TLE9222LCXUMA1 include an integrated bus failure detection (open, short-to-GND, short-to-VBAT) with diagnostic output, low standby current consumption for battery-sensitive applications, and an extended automotive temperature operating range. The PG-TSON-14-3 package exposes a thermal pad to the PCB for efficient heat removal through the copper pours. The TLE9222LCXUMA1 part number suffix -XUMA1 indicates reel packaging for high-volume surface-mount assembly. Typical applications for the TLE9222LCXUMA1 include electronic control units in chassis-by-wire systems (steering, braking, suspension), powertrain ECUs, ADAS sensor fusion controllers, and body-domain modules where deterministic, redundant communication is required. The combination of small package footprint, robust bus failure diagnostics, and low-power modes suits compact ECU designs where PCB area is at a premium. When designing with this device, follow Infineon's recommended PCB layout for the exposed thermal pad and use a star-grounding scheme for the bus shield connection. Always consult the manufacturer datasheet for the latest bus failure threshold values and EMC optimization recommendations for the differential bus termination network.

TLE9250XSJXUMA1 - 5Mbps CAN FD Transceiver PG-DSO-8 | Infineon
The Infineon TLE9250XSJXUMA1 is a high-speed CAN FD transceiver supporting data rates up to 5 Mbit/s, supplied in an 8-pin PG-DSO-8 package with operating voltage range 4.5 V to 5.5 V and an automotive temperature grade of -40 C to +150 C. It implements the physical layer according to ISO 11898-2 (2016) and is qualified to AEC-Q100 for automotive use, making it a drop-in interface between a microcontroller's CAN protocol controller and the differential bus wiring. The 5 Mbit/s CAN FD capability is essential for modern automotive networks carrying larger payloads such as ADAS sensor data, diagnostic telemetry, and gateway traffic. A CAN transceiver is a physical-layer interface IC that translates a microcontroller's digital CAN TXD/RXD logic-level signals into the differential CANH/CANL bus signaling required by the ISO 11898-2 standard. It also provides bus fault tolerance, dominant time-out, and ESD protection on the bus pins. In the broader hierarchy, the TLE9250XSJ sits between the protocol controller (an MCU or standalone CAN controller) and the wiring harness, protecting the controller from bus transients while driving the bus to the required differential voltage levels. Key features include very low electromagnetic emission (low EME) optimized for automotive EMI requirements, a low-power mode with remote wake-up via CAN bus activity, integrated bus pin ESD protection, dominant time-out for TXD stuck-dominant fault handling, and overtemperature shutdown. These features minimize external component count and simplify compliance with OEM EMC standards. The device also supports a 3.3 V compatible logic interface on TXD/RXD/EN/NSTB pins, allowing direct connection to modern low-voltage microcontrollers without level shifters. From an architecture standpoint, the TLE9250XSJ uses a fully integrated differential driver and receiver with separate supply pins for the digital interface (VDD, 3.3 V to 5 V) and the bus driver (VSUP, battery). This split-rail approach allows the bus to remain powered while the MCU side is off, supporting partial networking and low quiescent current in sleep mode. The internal slope control reduces radiated emissions at high bus speeds, eliminating the need for external common-mode chokes in most applications. Typical applications include automotive body control modules (BCM), gateway ECUs connecting multiple CAN sub-networks, electric vehicle battery management systems (BMS), ADAS sensor fusion nodes, and industrial CAN FD networks. Its wide supply range and automotive-grade qualification make it equally suitable for 12 V and 24 V truck/commercial-vehicle platforms. A key design consideration is the use of a common-mode choke and split bus termination (60 ohm between CANH and CANL plus two 30 ohm to ground) for optimum signal integrity at 5 Mbit/s. The non-sleep current is typically below 10 uA with remote wake-up enabled, making the part well-suited for partial networking where ECUs may be selectively powered down.

The Infineon TLE9351VSJXTMA1 is a high-speed CAN FD transceiver supporting ISO 11898-2, SAE J2284, and CAN FD up to 5 MBit/s, housed in an 8-pin PG-DSO-8 package. It operates from a 3.3V or 5V supply and includes a standby mode for low quiescent current, targeting automotive in-vehicle networks where reliable bus communication is mandatory. The part is AEC-Q100 qualified, confirming its suitability for harsh automotive electrical environments including load-dump, jump-start, and reverse-battery transients. A CAN transceiver (Controller Area Network transceiver) is a physical-layer IC that sits between a microcontroller's CAN protocol controller and the differential CAN bus. It converts single-ended TX/RX logic levels into the differential dominant/recessive bus states defined by ISO 11898-2 and rejects common-mode noise through high common-mode rejection. In the broader system hierarchy it belongs to: transceiver -> physical-layer interface -> in-vehicle networking IC -> automotive power management and communication IC -> semiconductor. CAN FD (Flexible Data-rate) extends classic CAN by increasing the data-phase bit rate while keeping the arbitration phase at the legacy bit rate, enabling larger payloads and faster ECU-to-ECU throughput. Key features include bus fault protection up to ±42V, thermal shutdown, undervoltage detection on VCC, and a low-power standby mode with bus wake-up capability. The receiver exhibits high common-mode immunity for reliable operation in noisy automotive harnesses, and the transmitter delivers a tightly controlled differential output with slope control to limit EMI. The PG-DSO-8 footprint is industry-standard for 8-pin CAN transceivers, simplifying PCB layout migration between competing solutions. Typical applications include body control modules, gateway ECUs, powertrain ECUs (where CAN FD is increasingly required), battery management system CAN interfaces, and ADAS sensor clusters. The standby mode enables quiescent current budgets in the microamp range, supporting always-on CAN networks that must wake the ECU upon bus activity. When designing with this part, place the VCC decoupling capacitor within 2mm of the VCC pin and route the CANH/CANL traces as a 100-ohm-impedance differential pair with ground stitching vias. Use a TVS diode such as NUP2105L on the bus pins to survive ISO 7637-2 pulse transients not covered by the IC's internal ±42V protection. The SPLIT pin, if used, requires a capacitor to ground.

The 8-pin SOIC and 3 mm × 3 mm SON options give designers a layout choice for both through-hole-style reflow and space-constrained modules. Architecturally the device combines a high-side driver with active current limiting, a recessive-side pull-up, a comparator-based receiver, and a state machine for wake-up pulse recognition; this integration removes the need for an external LIN pull-up resistor and a TVS diode in moderate-environment designs. Typical applications include body control modules, HVAC control panels, steering-wheel switch interfaces, door/window lift switches, seat-position memory modules, and LED lighting controllers. The wide VSUP range and integrated fault protection suit 12-V automotive battery systems including cold-crank and load-dump conditions. When designing with TLIN1029A-Q1, place a 100 nF decoupling capacitor close to VSUP and follow LIN bus layout guidelines (single-node stub, controlled impedance, ground return path) to meet EMC requirements per IEC 61967 and SAE J2962.

The combination of wide operating voltage, bus-fault ruggedness and AEC-Q100 Grade 1 qualification makes the part well suited to harsh automotive electrical environments including jump-start, load-dump and reverse-battery transients. Architecturally, the device combines a bandgap-referenced voltage regulator, a current-limited open-drain LIN driver with slew-rate control, a window comparator receiver, and a state-machine that handles dominant time-out, thermal shutdown, under-voltage lockout and wake-up detection. The integrated ESD cell on the LIN pin exceeds ±8 kV HBM, eliminating the need for an external TVS in most 12-V automotive LIN node designs. Typical applications include body control modules, door/window/seat/mirror modules, HVAC control nodes, steering column switches, lighting ECUs, and sensor/actuator nodes that must interface with a LIN master in an in-vehicle network. The receiver's higher 100 kbps capability also enables faster in-line programming of slave ECUs over the LIN bus. When designing with this device, ensure that VSUP is decoupled with a 100 nF ceramic capacitor close to the pin, and that the LIN bus pin is protected by the bus-pin ESD structure rather than an external TVS, since adding a TVS can load the bus and disturb the LIN waveshaping. The TXD pin must not be pulled high to VSUP, as TLIN1039-Q1 only provides an internal pull-down.

What is a LIN transceiver? A LIN (Local Interconnect Network) transceiver is a physical-layer (PHY) device that connects a microcontroller's UART-style logic domain to a single-wire, low-cost automotive communication bus. It typically integrates a wave-shaping transmitter, a comparator-based receiver, bus fault protection (against shorts to battery, ground, and adjacent LIN nodes), ESD protection, and a low-power wake-up mechanism. LIN sits hierarchically under in-vehicle networking alongside CAN (Controller Area Network), FlexRay, and Automotive Ethernet - LIN targets low-speed, low-cost nodes like door modules, mirror adjusters, and seat controllers, while CAN/Ethernet handle higher-bandwidth powertrain and ADAS domains. Key features include: integrated dominant-state timeout for fail-safe bus recovery, ±45V LIN bus fault tolerance (load-dump tolerant), ±15kV HBM ESD on the LIN pin per IEC 61000-4-2, ultra-low quiescent current in sleep mode, thermal shutdown, and an active-high WAKE input that wakes the device from sleep without MCU intervention. The part supports both 3.3V and 5V MCU logic via a separate VCC/VSUP rail scheme. The 8-pin SOIC (D) and 8-pin SON (DRB 3x3) packages provide small footprint for space-constrained body-electronics modules. Typical applications include automotive body control modules (BCM), HVAC control, door/window/seat modules, steering column controls, rain/light sensors, mirror adjusters, headlamp leveling, and interior lighting nodes. The part's AEC-Q100 Grade 1 qualification (-40C to +125C) makes it suited for underhood and cabin applications alike. Designers should ensure proper LIN bus termination (typically a master pull-up of 1kΩ plus a diode to VSUP, and a slave pull-up of 30kΩ in the device), use a 100nF X7R decoupling capacitor close to VSUP, and route the LIN trace as a short, stub-free single-ended line, twisted if possible, to minimize radiated emissions. The dominant-state timeout is configurable; refer to the datasheet's register or strap-setting description for the chosen mode.
