MAX3053 80V Fault-Protected, 2Mbps, Low Supply Current CAN Transceiver General Description Features The MAX3053 interfaces between the control area network 80V Fault Protection (CAN) protocol controller and the physical wires of the bus Three Operating Modes lines in a CAN. It is primarily intended for industrial systems High-Speed Operation up to 2Mbps requiring data rates up to 2Mbps and features 80V fault Slope Control Mode to Reduce EMI protection against shorts to high-voltage power buses. The (40kbps to 500kbps) device provides differential transmit capability to the bus 15A Low-Current Shutdown Mode and differential receive capability to the CAN controller. Autoshutdown when Device Is Inactive The MAX3053 has three different modes of operation: high-speed, slope control, and shutdown. High-speed Automatic Wakeup from Shutdown mode allows data rates up to 2Mbps. In slope control Thermal Shutdown mode, data rates are between 40kbps and 500kbps so Current Limiting the effects of EMI are reduced and unshielded twisted or parallel cable may be used. In shutdown mode, the Fully Compatible with the ISO 11898 Standard transmitter is switched off, and the receiver is switched to a low-current mode. An autoshutdown function puts the device in 15A shut- down mode when the bus or CAN controller is inactive for Ordering Information 47ms or greater. PART TEMP RANGE PIN-PACKAGE The MAX3053 is available in an 8-pin SO package and is MAX3053ESA -40C to +85C 8 SO specified for -40C to +125C operation.
