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 applications
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.
