摘要

PURPOSE: A circuit and a method for preventing an error operation of the opening and closing of a folder in a foldable portable wireless terminal to be automatically and manually used are provided to accurately open and close a sub-body irrespective of an automatic or manual mode. CONSTITUTION: A motor(240) provides a rotation force for automatically opening and closing a sub-body. A motor driving unit(210) drives the motor(240) according to a motor driving direction control signal. A counter electro-motive force preventing unit(230) opens or disconnects both sides of the motor(240) according to an automatic or manual mode and prevents a counter electro-motive force of the motor(240). A motor power control unit(220) controls a driving power of the motor(240).
