  • Isolation barrier communication system in a package for isolated gate driver communication
    Patent number: 11128294
    Abstract: A communication system includes a supply generator configured to generate a modulated supply according to a data transmission; a light emitting diode (LED) emulator including an emulator input coupled to the supply generator and an emulator output configured to output a sense voltage, wherein the emulator input is configured to receive a forward current derived from the modulated supply and translate the forward current into the sense voltage; a voltage comparator coupled to the emulator output and configured to receive the sense voltage and translate the sense voltage into a modulated output signal based on a communication voltage threshold; and a transmitter coupled to a comparator output and configured to receive the modulated output signal and generate a communication signal according to the data transmission based on the modulated output signal.
