Digital product charging alarm control circuit

The invention discloses a digital product charging alarm control circuit. A micro-control unit receives or transmits a wireless signal through a wireless module. The micro-control unit performs alarming of a buzzer SP1 by controlling a buzzer driving circuit. The micro-control unit receives the voltage signal fed back from an external power supply and the temperature signal at the charging head ofexternal equipment through an external temperature detecting circuit and an external temperature detecting circuit. The micro-control unit detects the current and controls charging of the output portthrough a current detection and control circuit and feeds back the control signal to the micro-control unit. A power supply management IC circuit controls the external power supply circuit to supplypower to the micro-control unit and the output port by cooperating with the micro-control unit. The invention belongs to the technical field of the charging alarm control circuit. The digital productcharging alarm control circu
