The TCAN1473A-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 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.
The device is pin compatible with classical CAN FD transceivers, such as TCAN1043A-Q1 or TCAN1043H-Q1 when INH_MASK feature is not used (INH_MASK pin is left floating or connected to GND).
