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.
