摘要：A circuit and method of processing malfunction of a hall effect switch used for

recognition of an open/close state of a flip or folder of a terminal. The circuit includes anoutput terminal of the hall effect switch for outputting a first-state or second-statesignal that indicates the open/close state of the flip or folder by sensing change of amagnetic field according to opening/closing of the flip or folder, a flip/folder-state inputterminal for transferring the first-state or second-state signal to a control section of theterminal, a first pull-up resistor connected to the flip/folder-state input terminal, aripple-removing capacitor connected to the flip/folder-state input terminal, and a secondresistor of which one terminal is connected to the output terminal of the hall effectswitch and the other terminal is connected to a connection point of the first resistor andthe capacitor.
