CHARGING WAKE-UP CIRCUIT CAPABLE OF PROVIDING A CONTROL VOLTAGE TO WAKE UP A DEVICE WHEN BEING CHARGED

A charging wake-up circuit includes a first switch, a second switch, a first resistor, a second resistor, and a third resistor. The first switch has a first terminal for receiving a first voltage, and a control terminal for receiving a second voltage. The second switch has a first terminal coupled to the second terminal of the first switch. The first resistor has a first terminal coupled to the control terminal of the second switch, and a second terminal coupled to the first terminal of the second switch. The second resistor has a first terminal coupled to the second end of the second switch, and a second terminal. The third resistor has a first terminal coupled to the second terminal of the second resistor and a device to provide a control voltage to the device to wake up the device, and a second terminal to receive a third voltage.
