CIRCUIT FOR PROCESSING WRONG OPERATION OF HALL EFFECT SWITCH USED FOR RECOGNIZING FLIP OR FOLDER OPEN/SHUT STATES OF TERMINAL AND METHOD THEREFOR |
摘要 |
PURPOSE: A circuit for processing a wrong operation of a hall effect switch used for recognizing flip or folder open/shut states of a terminal and a method therefor are provided to enable the terminal not to recognize that a flip or a folder is closed, though an output of the hall effect switch is changed by being influenced from a current, thereby removing possibility of cutting off a call. CONSTITUTION: A hall effect switch output end(300) senses a magnetic field change, and outputs the first state or the second state signal presenting open/shut states of a flip or a folder. A flip/folder state input end(310) transmits the first state or the second state signal to a controller of a terminal. The first pull-up resistor(R1) is connected to a contact point of the output end(300) and the input end(310). A ripple removing capacitor(C1) is connected to the contact point. One end of the second resistor(R2) is connected to the output end(300), and the other end thereof is connected to a contact point of the first resistor(R1) and the capacitor(C1).
