Circuit control device and method

Abstract

The embodiment of the invention discloses a circuit control device and method. The circuit control device is applied to electronic equipment. The device comprises a charging control module, a circuitswitching module, a capacitance detection module, a first change-over switch and a first polar plate, the first change-over switch comprises a first common end, a second end and a third end. The firstpolar plate is electrically connected with the first common end; the charging control module is electrically connected with the second end; the capacitance detection module is electrically connectedwith the third end; the circuit switching module is used for controlling the electric conduction state of the first change-over switch; when the first common end is electrically connected with the second end, the second common end is electrically connected with the second end; the charging control module carries out charging through the first polar plate and a second polar plate of the charging equipment, and the capacitance detection module obtains a first capacitance value through the first polar plate under the condition that the first common end and the third end are electrically conducted, so that the stacking of devices can be avoided and the safety is improved through the device.
