MAX3057

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 highvoltage 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. Highspeed 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.
