The MAX13041 ±80V fault-protected, high-speed controller area network (CAN) transceiver is ideal for highspeed automotive network applications where high reliability and advanced power management are required. The device links a CAN protocol controller to the physical bus wires of the controller area network and allows communication at speeds up to 1Mbps. The extended fault-protected voltage range of ±80V on CAN bus lines allows for use in +12V or +42V automotive, and higher voltage +24V and +36V mid-heavy truck applications. Advanced power management features make the MAX13041 ideal for automotive electronic control unit (ECU) modules that are permanently supplied by battery, regardless of the ignition switch position (clamp-30, Type-A modules). The device controls one or more external voltage regulators to provide a low-power sleep mode for an entire clamp-30 node. Wake-on CAN capability allows the MAX13041 to restore power to the node upon detection of CAN bus activity.
