POWER SUPPLY CONTROL CIRCUIT |
摘要 |
A power supply control circuit for an electronic device includes an input/output (I/O) microchip, a southbridge microchip and a power management unit. The control circuit is electrically connected to the I/O microchip and the southbridge microchip to output a driving voltage to the I/O microchip and the southbridge microchip. The power management unit includes a power management microchip electrically connected to the control circuit, the I/O microchip and the southbridge microchip. The power management microchip outputs a power on/off control signal to the southbridge microchip to power on/off the electronic device, and controls the control circuit to provide a driving voltage to the I/O microchip and the southbridge microchip when the electronic device is powered on and controls the control circuit to stop providing the driving voltage to the I/O microchip and the southbridge microchip when the electronic device is powered off.
