The MAX3051ESA+ is a low-supply-current CAN Transceiver, interfaces between the CAN protocol controller and the physical wires of the bus lines in a controller area network (CAN). It provides differential transmit capability to the bus and differential receive capability to the CAN controller. It 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 MAX3051ESA+ features four different modes of operation - 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 transceiver in low-current mode.
