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 5Mbps. 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 can 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.
When a wake-up pattern is detected on the bus or when a local wake-up is requested via the WAKE input, the TCAN1043xx-Q1 initiates node start-up by driving INH high. The TCAN1043xx-Q1 includes internal logic level translation via the VIO terminal to allow for interfacing directly to 3.3V or 5V controllers. The device includes many protection and diagnostic features including CAN bus line short-circuit detection and battery connection detection. The TCAN1043xx-Q1 meets the ESD and EMC requirements of IEC 62228-3 and J2962-2 without the need for additional protection components.
