TCAN1043G-Q1

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 V IO 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 TCAN1043xxQ1 meets the ESD and EMC requirements of IEC 62228-3 and J2962-2 without the need for additional protection components.
