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.

Abstract: A method for protecting a system including a driver integrated circuit includes receiving a driver input signal. The method includes driving an output signal externally to the driver integrated circuit. The output signal is driven based on the driver input signal and an indication of a delay between receipt of an edge of the driver input signal and arrival of a corresponding edge of the output signal at an output node coupled to a terminal of the driver integrated circuit.

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 has a first portion in a first voltage domain and a second portion in a second voltage domain. The first and second portions are coupled by an isolation communication channel. The isolated gate driver transmits across the isolation communication channel a serial word containing first drive strength information and simultaneously transmits gate information with the serial word across the isolation communication channel. The gate information indicates a state of a gate signal for a transistor coupled to the second portion of the isolated gate driver. A demodulator circuit demodulates a signal containing the gate information and the drive strength information transmitted across the isolation communication channel in the serial word. A gate signal output circuit coupled to the demodulator circuit supplies the gate signal based on the gate information with a drive strength of the gate signal being based on the drive strength information.
