Class D power amplifier` fault detecting method, involves generating comparison signals, and generating fault detection signal for indicating fault based on comparison between comparison signals
Class D power amplifier` fault detecting method, involves generating comparison signals, and generating fault detection signal for indicating fault based on comparison between comparison signals
The method involves generating a pulse width modulation signal, and generating an amplifier output signal based upon the pulse width modulation signal. Two comparison signals are generated based on respective comparisons between the pulse width modulation signal and the amplifier output signal. A fault detection signal is generated for indicating a fault based on a comparison between the comparison signals. An independent claim is also included for a circuit for detecting a fault in a class D power amplifier.
