MAX3051
+3.3V, 1Mbps, Low-Supply-Current
CAN Transceiver
General Description
The MAX3051 interfaces between the CAN protocol
controller and the physical wires of the bus lines in a
controller area network (CAN). The MAX3051 provides
differential transmit capability to the bus and differential
receive capability to the CAN controller. The MAX3051
is primarily intended for +3.3V single-supply applica-
tions that do not require the stringent fault protection
specified by the automotive industry (ISO 11898).
The MAX3051 features four different modes of opera-
tion: high-speed, slope-control, standby, and shutdown
mode. 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. This reduces the effects of EMI, thus
allowing the use of unshielded twisted or parallel cable.
In standby mode, the transmitter is shut off and the
receiver is pulled high, placing the MAX3051 in low-
current mode. In shutdown mode, the transmitter and
receiver are switched off.
The MAX3051 input common-mode range is from -7V to
+12V, exceeding the ISO 11898 specification of -2V to
+7V. These features, and the programmable slew-rate
limiting, make the part ideal for nonautomotive, harsh
environments. The MAX3051 is available in 8-pin SO
and SOT23 packages and operates over the -40°C to
+85°C extended temperature range.

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.
