PORTABLE ELECTRONIC DEVICE AND POWER CONTROL METHOD THEREFOR
First Claim
1. A portable electronic device, comprising:
- a power management unit configured to provide a first operating voltage, a second operating voltage and a third operating voltage;
a sense module powered by the first operating voltage and configured to obtain a sense event and provide a first control signal in response to the sense event when the portable electronic device is in a sleep mode;
a receiver module powered by the second operating voltage in response to the first control signal, wherein when the receiver module is powered by the second operating voltage, the receiver module is configured to obtain and recognize an input event and to provide a second control signal when the input event is recognized; and
an application processor powered by the third operating voltage in response to the second control signal.

Abstract
A portable electronic device includes a power management unit, a sense module, a receiver module and an application processor. The sense module powered by a first operating voltage from the power management unit provides a first control signal in response to a sense event when the portable electronic device is in a sleep mode. The receiver module is powered by a second operating voltage from the power management unit in response to the first control signal. When the receiver module is powered by the second operating voltage, the receiver module obtains and recognizes an input event and provides a second control signal when the input event is recognized. The application processor is powered by a third operating voltage from the power management unit in response to the second control signal.
