Abstract

The application discloses a charging circuit and an electronic device. The charging circuit includes a proximity sensor, an interrupt detection module, a switch control module, a switch, a resistor and a power supply. The proximity sensor is connected with the power supply through the resistor. If the switch is closed, the proximity sensor is connected with the power supply through the switch. Theproximity sensor is connected with the switch through the interrupt detection module and the switch control module in turn. The interrupt detection module outputs a generated low level interrupt signal to the switch control module if detecting that the input level of the contact of the proximity sensor is a low level, and outputs a generated falling edge interrupt signal to the switch control module if detecting that the input level of the contact of the proximity sensor changes from a high level to a low level. The switch control module can make the switch closed according to the low level interrupt signal or the falling edge interrupt signal. If the switch is closed, the power supply charges the proximity sensor. The charging circuit can improve the charging controllability of the proximity sensor.

Description

technical field [0001] The present application relates to the technical field of charging, in particular to a charging circuit and electronic equipment. Background technique [0002] Calling is the most basic function of the terminal. In order to further save the power consumption of the terminal during the call, the current terminal is generally equipped with a proximity sensor to detect whether the screen is close to the object when the terminal is talking, and to detect the brightness of the surrounding environment of the terminal. When the proximity sensor detects that the screen is far away from an object, the screen can be turned off to save power usage when the terminal is in a call. When the proximity sensor detects the light brightness of the surrounding environment of the terminal, the brightness of the screen can be adjusted according to the light brightness, so as to save the power consumption of the terminal during calls. [0003] In the related art, the chargi...
