TCAN1051-Q1 - Automotive Fault-Protected CAN FD Transceiver | Texas Instruments
MPN: TCAN1051-Q1 ✓ Hoạt độngTCAN1051-Q1 Tóm tắt
A CAN transceiver is the physical-layer interface between a CAN protocol controller (MCU) and the two-wire differential CAN bus. In the automotive hierarchy, the CAN bus connects ECUs such as engine control, body control, and infotainment modules. The transceiver converts TXD/RXD logic signals from the MCU into differential CANH/CANL signals on the bus and provides bus fault protection.
Key features include high on-chip IEC ESD protection, silent mode for reduced power consumption, and AEC-Q100 automotive qualification. The device is designed for harsh automotive environments, with fault protection that withstands bus transients. The flexible data-rate option enables CAN FD networks up to 5 Mbps, making it suitable for modern vehicle architectures that require higher bandwidth.
The TCAN1051 family uses a robust physical-layer design with protection diodes and a dominant time-out function, ensuring reliability under bus shorts and high-voltage transients. The device supports both 5 V and (in V variants) 3.3 V I/O reference voltage, allowing direct interface with low-voltage microcontrollers.
Typical applications include automotive body control modules, battery management systems, powertrain control, and industrial automation networks. The TCAN1051-Q1 is also widely used in diagnostics (OBD-II) and infotainment systems.
Design consideration: ensure proper termination (120 ohm) and place TVS diodes and bus filtering capacitors close to the on-board connectors to prevent transient events from propagating into the PCB.

Ghi chú thiết kế
Place TVS diodes and bus filtering capacitors as close to the on-board connectors as possible to prevent noisy transient events from propagating further into the PCB and system. Use a 120-ohm termination resistor at each end of the CAN bus.
Keep the CAN bus lines twisted and routed away from high-current switching nodes. Maintain proper ground planes and use a single-point ground for the transceiver. The differential nature of CAN rejects common-mode noise, but good layout is essential to preserve signal integrity.
The SOIC-8 package has moderate thermal dissipation. Ensure copper pours around the GND pin to help heat spreading. In high-density automotive ECUs, monitor junction temperature under continuous bus traffic, as the transceiver's current draw is low but can rise during bus fault conditions.
