The TCAN1473-Q1 is a Controller Area Network (CAN) transceiver that meets the physical layer requirements of the ISO 11898-2:2024 CAN specification with Signal Improvement Capability (SIC) functionality. The device reduces signal ringing at dominant-to-recessive edges and enables higher throughput in complex network topologies. SIC allows applications to extract the real benefit of CAN Flexible Datarate (CAN FD) by operating at 2Mbps, 5Mbps, and 8Mbps, even in large networks with multiple unterminated stubs.

The TCAN1473-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 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.

These devices are pin-compatible to 14-pin single-channel CAN FD transceivers, such as TCAN1043N-Q1 or TCAN1043H-Q1.
