摘要： A power-off circuit includes a power unit (10), a power management unit (20), an integrated circuit chip (IC chip, 40), a switching apparatus (30), and a clamp circuit (70). The switching apparatus produces and transmits a power-off instruction to the power management unit. The power management unit produces and transmits a power-off notice to the IC chip in accordance with the power-off instruction. And the IC chip feeds back a power-off affirmation in accordance with the power-off notice to the clamp circuit. The clamp circuit receives the power-off affirmation and produces and transmits interrupted power-off signals to the power management unit, till the power management unit completely cuts off power supplied from the power unit to the IC chip.

摘要： An exemplary electronic device capable of automatically selecting a power source includes two power ports configured to connect to external power sources and a battery compartment configured to receive a battery module. The voltage of the battery module is higher than at least one of the external power sources. The electronic device further includes a power selection module allocated between the battery module and the power port which selects the lower voltage. Three diodes are respectively located on the output path of the three power sources. A path switch that controls whether power to the device comes from the battery compartment or a power port is located between the anode of the battery compartment and the diode located on the output path of the battery module. Among the multiple power sources, the external power source providing a higher voltage is the first to be chosen to power the electronic device.
