MAX3051 +3.3V, 1Mbps, Low-Supply-Current CAN Transceiver General Description Benefits and Features The MAX3051 interfaces between the CAN protocol Use 3V Microcontroller with Same LDO controller and the physical wires of the bus lines in a Low +3.3V Single-Supply Operation controller area network (CAN). The MAX3051 provides Common-Mode Range Exceeds the ISO 11898 differential transmit capability to the bus and differential Standard (-2V to +7V) receive capability to the CAN controller. The MAX3051 Wide -7V to +12V Common-Mode Range is primarily intended for +3.3V single-supply applications Uses Minimal Board Space that do not require the stringent fault protection specified SOT23 Package by the automotive industry (ISO 11898). Flexible Operation Optimizes Performance The MAX3051 features four different modes of opera- and Power Consumption for Reduced Thermal tion: high-speed, slope-control, standby, and shutdown Dissipation mode. High-speed mode allows data rates up to 1Mbps. Four Operating Modes The slope-control mode can be used to program the slew High-Speed Operation Up to 1Mbps rate of the transmitter for data rates of up to 500kbps. Slope-Control Mode to Reduce EMI (Up to This reduces the effects of EMI, thus allowing the use 500kbps) of unshielded twisted or parallel cable. In standby mode, Standby Mode the transmitter is shut off and the receiver is pulled high, Low-Current Shutdown Mode placing the MAX3051 in low-current mode. In shutdown Robust Protection Increases System Reliability mode, the transmitter and receiver are switched off. 12kV Human Body Model ESD Protection Thermal Shutdown The MAX3051 input common-mode range is from -7V to Current Limiting +12V, exceeding the ISO 11898 specification of -2V to +7V. These features, and the programmable slew-rate Applications limiting, make the part ideal for nonautomotive, harsh Printers JetLink environments. The MAX3051 is available in 8-pin SO and Industrial Control and Networks SOT23 packages and operates over the -40C to +85C Telecom Backplane extended temperature range.
