2.3.5 TCAN1043A-Q1

The TCAN1043A-Q1 is a high-speed Controller Area Network (CAN) transceiver that meets the physical layer requirements of the ISO 11898-2:2016 highspeed CAN specification. The device supports both classical CAN and CAN FD data rates up to 8 megabits per second (Mbps).

The TCAN1043A-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 TCAN1043A-Q1, while monitoring the CAN bus. When a wake-up event is detected, the TCAN1043AQ1 initiates system start-up by driving INH high.

The TCAN1043A-Q1 features an SWE timer that enables a safe transition to Sleep mode after 4 minutes (tINACTIVE) of inactivity in Standby mode. This is designed so that the device is transitioned to low-power Sleep mode if the MCU fails to transition the device to Normal mode.
