TJA1057T/1Z - High-Speed CAN Transceiver | NXP SOIC-8
MPN: TJA1057T/1Z ✓ فعالTJA1057T/1Z نمای کلی
A CAN transceiver, also called a CAN physical-layer (PHY) chip, sits between a microcontroller's CAN protocol controller and the differential CANH/CANL bus wires. It transmits and receives differential signals, controls the slope of the dominant-to-recessive transitions, and provides ESD protection and bus-fault tolerance. The TJA1057 belongs to the Mantis CAN transceiver lineage that supersedes the older TJA1050; its position in the hierarchy is: CAN transceiver -> CAN interface IC -> automotive communication IC -> semiconductor.
Key features include very low-current standby mode with remote wake-up via bus activity recognition, high ESD robustness on the bus pins (typical >8 kV HBM), excellent electromagnetic compatibility (EMC) performance under both dominant and recessive states, and an integrated VIO supply pin (on related variants) allowing direct connection to 3.3 V microcontrollers. It supports an extended supply voltage range, an operating junction temperature range suitable for automotive under-hood environments, and a low-power sleep current that simplifies ECUs designed for quiescent-current budgets.
The device translates a single-ended TXD logic input from the CAN controller into a differential CANH/CANL output, and converts the bus differential back to a single-ended RXD logic output. It offers an SPLIT output pin (on related variants) for stabilizing the recessive bus level in networks with many nodes. The TJA1057 is a successor to the TJA1050 and is pin-compatible with several Mantis-family derivatives, simplifying PCB reuse across OEM programs.
Typical applications include automotive body control modules, CAN gateways and powertrain nodes, electric vehicle battery management system communication, industrial CAN-bus automation (CANopen, DeviceNet), and any application needing an ISO 11898-2 compliant differential CAN link to a microcontroller. The 1 Mbit/s nominal / 5 Mbit/s CAN FD fast-phase capability suits both classical CAN and modern CAN FD networks.
When designing with this IC, place the bus-side ESD/TVS protection and common-mode choke as close to the CANH/CANL pins as possible, and provide a solid ground pour under the SOIC-8 body. Decouple VCC with at least 100 nF and 4.7 µF local capacitance. Match the bus termination: 120 Ω between CANH and CANL at each end of the bus, plus optional split termination (60 Ω + 60 Ω to ground) for improved EMC.

کاربردهای معمول
TJA1057T/1Z مناسب است برای 6 کاربردs: Automotive Body Control Modules (BCM), Automotive Powertrain and Chassis CAN Bus, Electric Vehicle Battery Management CAN Bus, Industrial Automation (CANopen / DeviceNet), In-Vehicle Infotainment Gateway, Renewable Energy and Storage CAN Bus.
Automotive Body Control Modules (BCM)
The TJA1057T/1Z fits automotive body control modules where a CAN interface links the BCM to door modules, lighting, mirror controllers, and climate panels. Its 8-pin SOIC footprint and ISO 11898-2:2024 compliance ensure the part interoperates with other in-vehicle CAN ECUs on the 500 kbit/s classical CAN bus. The high ESD robustness and excellent EMC performance under both dominant and recessive states reduce the need for additional protection components. At 12 V vehicle battery operation with up to 5 Mbit/s CAN FD fast-phase support, the TJA1057T/1Z enables either legacy 500 kbit/s operation or migration to CAN FD where multiple data fields demand higher throughput. The low quiescent current in standby contributes to quiescent-current targets that have become strict in modern vehicles with always-on ECUs.

Automotive Powertrain and Chassis CAN Bus
In powertrain ECUs such as transmission control units, ABS/ESC controllers, and electric power steering, the TJA1057T/1Z connects the CAN controller to the high-speed differential bus. Its 1 Mbit/s (classical) and 5 Mbit/s (CAN FD fast phase) data-rate support covers SAE J2284-1 to SAE J2284-5 networks used in powertrain and chassis domains. The transceiver's differential drive strength and stable recessive bus bias suppress ringing on long network cables that run through the chassis. With an automotive-grade operating temperature range and NXP's quality support, the TJA1057T/1Z is widely accepted by OEMs. The SOIC-8 footprint supports miniaturized ECU PCB layouts where every square millimeter matters.

Electric Vehicle Battery Management CAN Bus
Inside a battery management system (BMS), the TJA1057T/1Z provides a CAN FD physical layer linking the master BMS controller to cell-monitoring modules distributed through the pack. CAN FD at up to 5 Mbit/s in the fast phase enables bulk transfer of per-cell voltage and temperature frames during diagnostic or fast-charge events. The transceiver's differential CANH/CANL signals allow robust communication across the long harness that snakes between modules in a high-voltage battery pack, where common-mode noise from inverter switching is severe. NXP's strong ESD rating on bus pins reduces the risk of field failures when service technicians connect chargers. The SOIC-8 small footprint permits placement on tight cell-module PCBs.

Industrial Automation (CANopen / DeviceNet)
In industrial CANopen and DeviceNet nodes such as programmable logic controllers, motor drives, sensors, and remote I/O blocks, the TJA1057T/1Z provides the high-speed physical layer. CANopen (typically 125 kbit/s to 1 Mbit/s) and DeviceNet (125 kbit/s, 250 kbit/s, 500 kbit/s) both rely on the ISO 11898-2 standard that the TJA1057T implements. Its low standby current suits remote I/O blocks powered through the bus or through small local supplies. The wide common-mode range supports long trunk cables (with proper cable and termination) common in factory automation. NXP's strong support ecosystem eases multi-vendor CAN network integration for industrial OEMs.

In-Vehicle Infotainment Gateway
Telematics control units and infotainment gateways use the TJA1057T/1Z to bridge CAN-FD traffic between the chassis domain (500 kbit/s, 1 Mbit/s) and the infotainment domain that aggregates data for HMI displays. Its strong EMC performance minimizes spurious emissions on the bus and helps gateways pass conducted/radiated automotive EMC tests. The SOIC-8 small footprint supports placement alongside the gateway MCU and an additional cellular modem on the same PCB. CAN FD capability future-proofs the gateway for higher-throughput chassis-side upgrades. Combined with external interface ICs, the TJA1057T/1Z supports seamless bridging across multiple bus segments.

Renewable Energy and Storage CAN Bus
Solar inverters, wind turbine controllers, and grid-scale battery storage systems use the TJA1057T/1Z to communicate internal module status (cell voltages, temperatures, fault flags) over a CAN bus. CAN FD compatibility allows larger diagnostic frames during service events without slowing normal telemetry throughput. The wide input-voltage tolerance and industrial -40°C to +125°C operating range suit outdoor cabinet installations exposed to temperature extremes. Through careful bus termination (120 Ω between CANH and CANL at both cable ends), the TJA1057T/1Z supports communication across the long cables typical of PV/string-monitoring layouts. NXP's strong second-source ecosystem eases multi-year renewable energy deployments.

یادداشت‌های طراحی
Place the TVS diode array and common-mode choke for CANH and CANL as close to the bus pins (pins 6 and 7) as possible. Provide a continuous, unbroken ground pour under the SOIC-8 body to keep the bus-side high-frequency return impedance low. Isolate the digital GND reference of the CAN controller from the bus-side reference with a single-point bridge near the IC GND pin (pin 2). Avoid routing digital signals (TXD, RXD, MCU traces) parallel and close to the CANH/CANL differential pair for more than a few millimeters.
Decouple VCC (pin 3) with at least a 100 nF X7R ceramic capacitor right at the pin and a 4.7 µF X5R bulk capacitor within 10 mm. If the SPLIT/VIO pin (pin 5) is used, add its own 100 nF decoupling cap. Match the differential pair impedance (typically 100 Ω to 120 Ω differential) and keep length-matched within 5 mm to avoid skew. Bus termination of 120 Ω between CANH and CANL is required at each end of the bus; split termination of 60 Ω + 60 Ω to ground is recommended for better EMC.
Estimate: without local TVS protection on CANH/CANL, ESD events during cable handling can drive bus pins beyond the datasheet absolute-maximum. Always add a bidirectional TVS array such as the PESD1CAN (NXP) or equivalent on the bus side. Do not exceed VCC max; the TJA1057 family is 5 V typical and VIO-tolerant variants allow 3.3 V MCU logic connection. Do not skip the standby-mode (pin 8) pull configuration: leaving it floating can cause the part to enter standby unpredictably. When designing for CAN FD at >2 Mbit/s, ensure bit-time symmetry by choosing the TJA1057B variant or equivalent.
The TJA1057 is designed for low EMC emissions, but the PCB layout still controls radiated emissions. Keep the CANH/CANL trace pair on the same layer with ground guard traces on either side for the portion inside the housing. Minimize stubs at the transceiver connection - use a T-connection only for nodes in the middle of the bus. Common-mode chokes (e.g., DLW43SH series from Murata or equivalent) significantly reduce common-mode emissions on long cables, but should be matched with the chosen bus topology to avoid signal integrity issues at high data rates.
