Abstract
A method of initiating a reset sequence for a MEMS capacitive microphone. The method includes monitoring an output of a microphone and detecting a mute condition in the output of the microphone indicative of a fault condition. The method also includes activating a timing circuit. The timing circuit is configured to indicate when a certain time period since the initiation of the timing circuit has elapsed. Upon expiration of the time period indicated by the timing circuit, a microphone reset sequence is initiated.
