MAX3051EKA+T Description

In a controller area network, the MAX3051 serves as an interface between the CAN protocol controller and the actual bus lines' wires (CAN). The MAX3051 equips the CAN controller with differential receive capability and the bus with differential transmit capability. The MAX3051 is primarily designed for +3.3V single-supply applications without the strict fault protection requirements set forth by the automotive sector (ISO 11898).

Four operating modes are available on the MAX3051: high-speed, slope-control, standby, and shutdown mode. Data rates up to 1Mbps are allowed in high-speed mode. The transmitter's slew rate can be tuned for data rates up to 500kbps using the slope-control mode. As a result, unshielded twisted or parallel cable can be used because the effects of EMI are lessened. The MAX3051 enters low-current mode when the transmitter is turned off and the receiver is pushed high. The transmitter and receiver are turned off when in shutdown mode.

The ISO 11898 specification of -2V to +7V is exceeded by the MAX3051 input common-mode range of -7V to +12V. The item is perfect for severe situations outside of the automotive industry thanks to these capabilities and the configurable slew-rate limiting.
