Automotive Enhanced CAN FD Transceiver with Watchdog, LIMP and Bus Diagnostics (VSON-14)
The TCAN1144-Q1 is an SPI-configured enhanced CAN FD transceiver for automotive ECUs. Beyond the physical layer (ISO 11898-2:2016), it integrates a watchdog (timeout, window and Q&A), bus fault diagnostics and reporting, and a programmable INH/LIMP pin, helping reduce external components in functional-safety designs. It offers ±58 V bus fault protection and VIO support for 1.8 V, 3.3 V or 5 V controllers. For selective wake (partial networking), TI offers the TCAN1145-Q1 / TCAN1146-Q1.
