Portable device and wireless power charging system for portable device
First Claim
1. A portable device, comprising:
- a power receiving unit to receive a first energy or a second energy from a wireless power transmitter, the first energy being used to perform a communication function and a control function, the second energy being used to charge a battery, and the wireless power transmitter being configured to wirelessly transmit a power;
a voltage generator to generate a wake-up voltage from the first energy, or to generate a voltage for charging the battery from the second energy;
a controller to perform the communication function and the control function, the controller being activated by the wake-up voltage; and
a communication unit to perform a communication with the wireless power transmitter based on a control of the controller.
