    Abstract: An integrated circuit includes a demodulator to demodulate a signal simultaneously transmitted over an isolation communication channel and obtain gate information and configuration information. The demodulator includes a gate demodulation path and a configuration demodulation path. The received signal oscillates at a first frequency to represent a first state, oscillates at different frequencies to represent a seconds state, oscillates at a third frequency (or third and fourth frequencies), which are lower than the first frequency, to represent a third state, and the received signal is steady state to represent a fourth state. The gate demodulation path detects the first and second states. The configuration demodulation path includes first and second sub-demodulation paths. An envelope detector in the first sub-demodulation path detects the second state and the second sub-demodulation path detects the third state. The configuration demodulation paths uses an output of the gate demodulation path.

    Abstract: An isolated gate driver includes a first input terminal to receive gate information and one or more input terminals to receive configuration information. A modulation circuit generates a modulated signal having four possible states, each of the four possible states corresponding to a different unique pair of values of the gate information and the configuration information. The modulation circuit represents two of the states using on-off keying (OOK) while the configuration information is at a first value and represents two of the states as a modification to the OOK modulation based on the configuration information being at a second value. The modulated signal is sent over an isolation communication channel coupling a transmitter and receiver of the isolated gate driver.
