The TCAN1043xx-Q1 meets the physical layer requirements of the ISO 11898–2 (2016) High Speed Controller Area Network (CAN) specification providing an interface between the CAN bus and the CAN protocol controller. These devices support both classical CAN and CAN FD up to 2 megabits per second (Mbps). Devices with part numbers that include the suffix “G” are designed for CAN FD data rates up to 5 Mbps. The TCAN1043xx-Q1 allows for system-level reductions in battery current consumption by selectively enabling (via the INH output pin) the various power supplies that may be present on a node. This allows an ultra-low-current sleep state in which power is gated to all system components except for the TCAN1043xx-Q1, which remains in a low-power state monitoring the CAN bus.
