Abstract

The invention relates to the technical field of chargers, in particular to an overheating protection device and method using MOS tube conduction resistance; The holding plate is opposed to the end of the placement frame away from the jacking spring. The temperature sensor monitors the temperature of the wireless charger body in real time and transmits the temperature data to the main control board. When the main control board judges that the temperature of the wireless charger body has risen abnormally When it is high, use the main control board to control the rotation mechanism to start, so as to drive the resisting plate to rotate, and then make the resisting plate break away from the placement frame, and the jacking spring is in a compressed state under normal conditions. The self-recovery force of the coil drives the frame to rotate, and the mobile phone in the frame is separated from the coil, thereby stopping the power supply.

Description

technical field [0001] The present invention relates to the technical field of chargers, and in particular, to a device and method for overheating protection using a MOS transistor on-resistance as a charger. Background technique [0002] The wireless charger is a device that uses the principle of electromagnetic induction to charge. Signal and convert the electromagnetic signal into current, and control the output current through the on-resistance of the MOS tube, so as to achieve the purpose of wireless charging. [0003] However, in the process of charging the mobile phone, the wireless charger will overheat the battery. With the accumulation of battery heat, it is easy to induce spontaneous combustion and explosion accidents of the battery. SUMMARY OF THE INVENTION [0004] The purpose of the present invention is to provide a device and method for overheating protection using MOS transistor on-resistance as a charger, so as to solve the problem of overheating of the b...
