Automotive low-power signal improvement CAN FD transceiver

The Texas Instruments TCAN1473-Q1 is a high-speed CAN transceiver that meets the physical layer needs of the ISO 11898-2:2024 high-speed CAN specification. The device supports classical CAN and CAN FD data rates up to 8Mbps.

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