CAN Transceiver Tolerates High Voltage Transients

Suitable for use in 12V and 24V automotive systems, the MCP2551 ISO11898-compliant, high-speed CAN transceiver can withstand short-circuit voltages from -40V to 40V and transient voltages from -250V to 250V. The transceiver employs an externally controlled output slope capability to reduce RFI emissions. Using a lower CAN speed—126 kb/s or lower—users can deploy networks without shielded, twisted pair wiring. Using the slope- control input, differential output changes can be controlled to the point where non-shielded cable can be used. Other features include thermal shutdown circuitry that disables the output drivers when the junction exceeds 165°C. In eight-pin PDIP and SOIC packages, the CAN transceiver costs $1.29 each/1,000.
