The TCAN1473-Q1 is a high-speed Controller Area Network (CAN) transceiver that meets the physical layer requirements of the ISO 11898-2:2024 high-speed CAN specification. The device supports both classical CAN and CAN FD data rates up to 8 megabits per second (Mbps).

The TCAN1473-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 allows a low-current sleep state in which power is gated to all system components except for the TCAN1473-Q1, while monitoring the CAN bus. When a wake-up event is detected, the TCAN1473-Q1 initiates system start-up by driving INH high.
