Texas Instruments TCAN1167-Q1 Automotive CAN FD SBC

Texas Instruments TCAN1167-Q1 Automotive CAN FD System Basis Chip (SBC) is a high-speed Controller Area Network (CAN) system basis chip (SBC) that meets the physical layer requirements of the ISO 11898-2:2016 high-speed CAN specification. The transceiver supports classical CAN and CAN FD networks up to eight megabits per second (Mbps).

The Texas Instruments TCAN1164-Q1 supports a wide input supply range and integrates a 5V LDO output. The 5V LDO output (V_CCOUT) supplies the CAN transceiver voltage internally and additional current externally.

The TCAN1167-Q1 allows for system-level reductions in battery current consumption by selectively enabling the various power supplies that may be present on a system via the INH output pin. This feature allows an ultra-low-current sleep state where power is gated to all system components except for the TCAN1167-Q1 while monitoring the CAN bus. When a wake-up event is detected, the TCAN1167-Q1 initiates system start-up by driving INH high.
