Abstract
The disclosure provides an electronic device. The electronic includes an internal battery, a first converter, a processor and a control circuit. The first converter is used to convert electrical power provided by the internal battery or provided by an external power source into a first power signal. The processor operates in an “ON-state” or switches to an “OFF-state”. The control circuit is used to control the first converter, so that the first converter selectively provides the first power signal to the processor.
Claims15
An electronic device, comprising:
- an internal battery;
- a first converter, for converting an electrical power provided by the internal battery or an electrical power provided by an external power source into a first power signal;
- a processor, operating in a ON-state or switching to a OFF-state according to the first power signal;
- and
- a control circuit, for controlling the first converter to make the first converter selectively provide the first power signal to the processor, and the control circuit is configured to:
- provide an enable signal to control the first converter, wherein when the enable signal has a high voltage level, the first converter provides the first power signal to the processor;
- and
- when the external power source does not provide the electrical power and the processor enters a shut-down procedure, and a first predefined period elapses after the shut-down procedure is completed, lower the enable signal to a low voltage level, wherein when the shut-down procedure is completed, the processor switches to the OFF-state.
