MAX13051
±80V Fault-Protected Can Transceiver
with Autobaud
General Description
The MAX13051 ±80V fault-protected CAN transceiver
with autobaud is ideal for device net and other industri-
al network applications where overvoltage protection is
required. The MAX13051 provides a link between the
CAN protocol controller and the physical wires of the
bus lines in a control area network (CAN).
The MAX13051 features three different modes of opera-
tion: high speed, slope control, and standby. High-
speed mode allows data rates up to 1Mbps. The
slope-control mode can be used to program the slew
rate of the transmitter for data rates of up to 500kbps,
reducing the effects of EMI and allowing the use of
unshielded-twisted or parallel cable. In standby mode,
the transmitter shuts off and a low-power receiver moni-
tors the bus, waiting for a wake-up signal.
The MAX13051 provides a transmitter data (TXD) domi-
nant timeout function that prevents erroneous CAN con-
trollers from clamping the bus to a dominant level if the
TXD input is held low for greater than 1ms. The
MAX13051 also provides an autobaud feature allowing
the microcontroller to compute the incoming baud rate
without destroying CAN protocol communication. The
MAX13051 input common-mode range is greater than
±12V, exceeding the ISO 11898 specification of -2V to
+7V, and features ±6kV Human Body Model protection,
making these devices ideal for harsh environments. The
MAX13051 is available in an 8-pin SO package and is
specified from the -40°C to +85°C and -40°C to +125°C
temperature ranges.

ABSOLUTE MAXIMUM RATINGS
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
