TJA1041AT,512

Drivers, Receivers, Transceivers Overview

The TJA1041AT,512 is a high-speed CAN transceiver providing an interface between the protocol controller and physical bus in automotive applications. It supports communication speeds up to 1 Mbit/s and complies with ISO 11898 standards. The device features low-power management with Standby and Sleep modes, local/remote wake-up, and source recognition. It includes protection against short circuits, overtemperature, and undervoltage on VCC, VI/O, and VBAT pins. The I/O levels automatically adapt to host controller supply voltages between 2.8 V and 5.25 V. Packaged in an SO14 plastic small outline package (SOT108-1), it ensures excellent EMC performance and passive behavior when supply voltage is off.

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix '512' against official NXP documentation to confirm packaging details such as reel size or tape-and-reel specifications. Ensure compatibility with existing PCB footprints for the SO14 package. Confirm that the component meets current environmental compliance requirements for your target market before finalizing procurement orders.

Drivers, Receivers, Transceivers Selection Notes

Select this transceiver for nodes requiring advanced power management and diagnostic capabilities in partially powered networks. It is suitable for systems needing automatic I/O level adaptation without external logic. Consider its passive behavior during unpowered states and robust protection features for critical automotive environments where reliability and fault detection are paramount.

Drivers, Receivers, Transceivers Part Context

The TJA1041A belongs to NXP's high-speed CAN transceiver family designed for automotive use. It offers enhanced EMC performance and low power consumption compared to earlier generations. The device integrates multiple fail-safe mechanisms and diagnostic flags accessible via the ERR pin, making it ideal for complex network topologies requiring high system reliability and advanced power control strategies.

Drivers, Receivers, Transceivers Replacement Considerations

Direct replacements include the TJA1041T variant, which shares identical electrical characteristics but may differ in packaging or reel configuration. Verify pinout compatibility and functional equivalence before substitution. Ensure any alternative component maintains support for the required operating modes and diagnostic features specified in the original design.
