Texas Instruments TCAN1043xx-Q1 Fault Protected CAN Transceiver

Texas Instruments TCAN1043xx-Q1 Fault Protected CAN Transceiver meets the physical layer requirements of the ISO 11898–2 (2016) High-Speed Controller Area Network (CAN) specification. These transceivers provide 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 5Mbps. The Texas Instruments 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 feature 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.
