The TCAN1473A-Q1 is a high-speed Controller Area Network (CAN) transceiver that meets the physical layer requirements of the ISO 11898-2:2023 high-speed CAN specification including the SIC specification. The device supports both classical CAN and CAN FD (flexible data rate) data rates up to 8 Megabits per second (Mbps).

The TCAN1473A-Q1 reduces signal ringing at the dominant-to-recessive edge and enables higher throughput in complex network topologies. SIC allows the applications to extract the real benefit of CAN FD by operating at 2Mbps, 5 Mbps, or beyond in large networks with multiple unterminated stubs. The device is pin compatible with classical CAN FD transceivers, such as TCAN1043A-Q1 or TCAN1043-Q1 when INH_MASK feature is not used (INH_MASK pin is left floating or connected to GND).

The TCAN1473A-Q1 allows for system-level reductions in battery current consumption by selectively enabling the various power supplies that can 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 TCAN1473A-Q1, while monitoring the CAN bus. When a wake-up event is detected, the TCAN1473A-Q1 initiates system start-up by driving INH high.

The TCAN1473A-Q1 features an SWE timer that enables a safe transition to Sleep mode after 4 minutes (tINACTIVE) of inactivity in Standby mode. This makes sure the device is transitioned to low-power Sleep mode if the MCU fails to transition the device to Normal mode.
