High-speed CAN transceiver withstands large transients

10 September 2002 Telecoms, Datacoms, Wireless, IoT

Microchip claims its new high-speed CAN transceiver withstands short-circuit voltages from -40 to +40 V and voltage peaks from -250 to +250 V without damaging the circuit. Suitable for 12 and 24 V systems, the MCP2551 is ideal for automotive and industrial applications serving as the interface between a CAN-protocol controller and the system's physical bus. The device provides a differential transmit and receive capability and adheres to the stringent requirements of the ISO11898 communication standard supporting speeds of up to 1 Mbps.

The device features an externally controlled output slope capability for reduced RFI emissions. By using the slope control input pin, CANH and CANL differential output signal changes can be controlled such that it is possible to implement networks with lower cost, nonshielded wiring while remaining below acceptable levels of radiated emissions. CANH and CANL are protected against battery short-circuits and electrical transients preventing destruction of the transmitter output stage. The device is further protected from excessive current loading by automatic thermal shutdown circuitry that disables the output drivers when the junction temperature exceeds a nominal limit of 165°C. All other parts of the chip remain operational while the chip temperature is lowered due to the decreased power dissipation in the transmitter outputs. The devices are available in 8-pin PDIP and SOIC.
