±80V Fault-Protected High-Speed CAN Transceiver
with Low-Power Management and Wake-On CAN
General Description
The MAX13041 ±80V fault-protected, high-speed con-
troller area network (CAN) transceiver is ideal for high-
speed 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 automo-
tive, and higher voltage +24V and +36V mid-heavy truck
applications. Advanced power management features
make the MAX13041 ideal for automotive electronic con-
trol 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.
The MAX13041 is functionally compatible with the
Philips TJA1041A and is a pin-to-pin replacement with
improved performance. The MAX13041 is available in a
14-pin SO package, and operates over the -40°C to
+125°C automotive temperature range.
