The TCAN1044x-Q1 devices are high speed Controller Area Network (CAN) transceivers that meet the physical layer requirements of the ISO 11898-2:2016 high speed CAN specification providing an interface between the CAN bus and a CAN protocol controller. The TCAN1044x-Q1 devices support both classical CAN and CAN FD networks up to 5 megabits per second (Mbps). The device part numbers with the "V" suffix include internal logic level translation via the VIO terminal to allow for interfacing directly to 1.8 V, 3.3 V, or 5 V controllers. The devices have a low-power standby mode which supports remote wake-up via the ISO 11898-2:2016 defined wake-up pattern (WUP). The TCAN1044x-Q1 devices include many protection and diagnostic features including thermal shutdown (TSD), driver dominant timeout (TXD DTO), and bus fault protection up to ±42 V.
