Overview
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 will initiate 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 3.3 V or 5 V 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.
