More Information
Summary:The utility model relates to the field of control and regulation circuits, in particular to a wake-up circuit, which comprises a manual switch module and a USB (Universal Serial Bus) starting module, the manual switch module is connected to an enabling pin of the MCU chip, and the manual switch module can output a turn-on signal to the enabling pin of the MCU chip so as to enable the MCU chip to be powered on and started, or output a turn-off signal to the enabling pin of the MCU chip so as to enable the MCU chip to be powered off and turned off; and the USB starting module is connected to an enabling pin of the MCU chip, and when external power supply voltage is connected to the USB starting module, a starting signal can be output to the enabling pin of the MCU chip so that the MCU chip can be powered on and started. The POS machine has the advantage that the POS machine can be automatically started when the USB is connected for power supply. 本申请涉及控制和调节电路的领域，尤其是涉及一种唤醒电路，其包括手动开关模块和USB启动模块；手动开关模块，连接于MCU芯片的使能引脚
