General Description
The MAX3050/MAX3057 interface between the CAN
protocol controller and the physical wires of the bus
lines in a controller area network (CAN). They are pri-
marily intended for automotive systems requiring data
rates up to 2Mbps and feature ±80V fault protection
against short circuits in high-voltage power buses. They
provide differential transmit capability to the bus and
differential receive capability to the CAN controller.
The MAX3050/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 transmit-
ter and receiver are switched off.
The MAX3050 has an AutoShutdown function that
puts the device into a 15μA shutdown mode when the
bus or CAN controller is inactive for 4ms or longer.
The MAX3050/MAX3057 are available in an 8-pin SO
package and are specified for operation from -40°C to
+125°C.
