Texas Instruments TCAN1162x-Q1 Automotive CAN FD Transceivers
Texas Instruments TCAN1162x-Q1 Automotive CAN FD Transceivers are high-speed controller area network (CAN) system basis chips (SBC) that meet the physical layer requirements of the ISO 11898-2:2016 high-speed CAN specification. The TCAN1162x-Q1 supports classical CAN and CAN FD networks up to eight megabits per second (Mbps).
The TCAN11623-Q1 and TCAN11625-Q1 support a wide input supply range and integrate some form of an LDO output. The TCAN11625-Q1 has a 5V LDO output (VCCOUT) which supplies the CAN transceiver voltage internally and additional current externally. The TCAN11623-Q1 has a 3.3V LDO output (VLDO3), supplied from the 5V LDO, supporting external loads.
The Texas Instruments TCAN1162x-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 TCAN1162x-Q1 while monitoring the CAN bus. When a wake-up event is detected, the TCAN1162x-Q1 initiates system start-up by driving INH high.
