MAX3050/MAX3057
±80V Fault-Protected, 2Mbps, Low-Supply
Current CAN Transceivers
General Description
The MAX3050 and MAX3057 interface between the
CAN protocol controller and the physical wires of the bus
lines in a control area network (CAN). They are primarily
intended for systems requiring data rates up to 2Mbps
and feature ±80V fault protection against shorts in high-
voltage power buses. They provide differential transmit
capability to the bus and differential receive capability to
the CAN controller.
The MAX3050 and MAX3057 have four modes of operation:
high speed, slope control, standby, and shutdown. High-
speed mode allows data rates up to 2Mbps. In slope-control
mode, data rates are 40kbps to 500kbps, so the effects of
EMI are reduced, and unshielded twisted or parallel cable
can be used. In standby mode, the transmitters are shut off
and the receivers are put into low-current mode. In shutdown
mode, the transmitter and receiver are switched off.
The MAX3050 has an AutoShutdown™ function that puts
the device into a 15ms shutdown mode when the bus or
CAN controller is inactive for 4ms or longer.
The MAX3050 and MAX3057 are available in an 8-pin
SO package and are specified for operation from -40°C
to +125°C.

The MAX3050 and MAX3057 require no special layout
considerations beyond common practices. Bypass VCC to
GND with a 1μF ceramic capacitor mounted close to the
IC with short lead lengths and wide trace widths.
