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.
