The MAX3053 interfaces between the control area net-
work (CAN) protocol controller and the physical wires of
the bus lines in a CAN. It is primarily intended for indus-
trial systems requiring data rates up to 2Mbps and fea-
tures ±80V fault protection against shorts to
high-voltage power buses. The device provides differ-
ential 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.
