WIRELESS POWER SYSTEM

摘要

A wireless power system can include wireless power receive circuitry for generating power from a wireless signal, and a wireless power transceiver for communicating with a wireless power transmission unit. The wireless power system can transition from an idle state to different power management states depending on whether or not communication has been established with the wireless power transmission unit. Different modules can be activated, different supply voltages, and different clock signal rates can be used in different power management states.

主权项

1. A device comprising:
wireless power receive circuitry to generate power from a received wireless power signal; a first wireless power transceiver configured to communicate with a second wireless power transceiver included in a wireless power transmission unit; a processing module coupled to the wireless power receive circuitry and the first wireless power transceiver, the processing module configured to:
transition from an idle state to a first power management state in response to the device being enabled and determining that communication has been established with the wireless power transmission unit; andtransition from an idle state to a second power management state in response to the device being enabled and determining that communication has not been established with the wireless power transmission unit.
