APPARATUS AND METHOD FOR DETECTING INSERTION ANOMALY OF AN AUDIO JACK

摘要

Apparatus and methods for detecting audio jack connection anomalies such as moisture or a partial insertion of an audio jack plug with an audio jack receptacle are provided. In an example, a method for detecting an audio jack insertion anomaly can include ramping on a first detection current source of a detection circuit coupled to a detection terminal of a first audio jack connector, receiving a reference information at a comparator of the detection circuit, receiving a voltage of the detection terminal at the comparator, providing comparison information at an output of the comparator, the comparison information indicative of a comparison of the voltage of the detection terminal and the reverence information, and wherein a first state of the comparison information indicates the audio jack insertion anomaly is due to moisture at the first audio jack connector.
