Abstract

A controller area network including one or more first network nodes biased from a first power supply voltage, and a second network node biased from a second, lower, power supply voltage. The second network node includes a transmitter driving a differential voltage onto bus lines to communicate a dominant bus state at a second dominant state common mode voltage, a receiver coupled to the bus lines, sense circuitry to sense a common mode voltage at the bus lines, and control circuitry to control a recessive state common mode voltage in response to the sensed dominant state common mode voltage.
