MAX3053
±80V Fault-Protected, 2Mbps,
Low Supply Current CAN Transceiver
General Description
The MAX3053 interfaces between the control area network
(CAN) protocol controller and the physical wires of the bus
lines in a CAN. It is primarily intended for industrial systems
requiring data rates up to 2Mbps and features ±80V fault
protection against shorts to high-voltage power buses. The
device provides differential transmit capability to the bus
and differential receive capability to the CAN controller.
The MAX3053 has three different modes of operation:
high-speed, slope control, and shutdown. High-speed
mode allows data rates up to 2Mbps. In slope control
mode, data rates are between 40kbps and 500kbps so
the effects of EMI are reduced and unshielded twisted
or parallel cable may be used. In shutdown mode, the
transmitter is switched off, and the receiver is switched to
a low-current mode.
An autoshutdown function puts the device in 15μA shut-
down mode when the bus or CAN controller is inactive for
47ms or greater.
The MAX3053 is available in an 8-pin SO package and is
specified for -40°C to +125°C operation.
