A power management circuit based on autonomous control

Abstract

Based on the concept of external triggering and internal autonomous control, by using the semiconductor device with switching characteristics, using the function of capacitor voltage regulation and energy storage, and fully utilizing the charge and discharge function of the capacitor, the author introduces a new type of power management circuit. The circuit realizes the function of the device to independently control the power supply that is turned off when the storage, standby, etc. do not need to work. When the device needs to work, the power supply switch of the circuit is triggered by the external condition, and the power supply automatically supplies power to the device through the circuit. Therefore, the function of energy saving and energy saving of the device is realized, the battery life capability of the battery is improved, the loss of the power supply of the device is greatly reduced, and the technical problem that the battery of the current device is largely lost during idle and standby periods is solved, and the environmental protection and energy saving has Certain meaning.
