Abstract
A system and method providing for delayed initialization of a device in a wireless charging environment. In certain aspects, a device is configured to detect power wirelessly received from a power transmitter. The device may further wirelessly transmit a message to the power transmitter in response to the received power, further determining that a power level of the received power has been adjusted in response to the message. In response to the determining the power level has been adjusted, a controller that is powered by the adjusted power level may be initialized.
Claims30
A method of operating a device, comprising:
- detecting power wirelessly received from a power transmitter;
- wirelessly transmitting a message to the power transmitter in response to the received power;
- determining that a power level of the received power has been adjusted in response to the message;
- and
- initializing, in response to the determining, a controller that is powered by the adjusted power level.
An apparatus configured for performing the delay of an initialization sequence of a device, that apparatus comprising:
- a power management circuit operably connected to a wireless power receiver circuit and configured to detect power wirelessly received from a power transmitter;
- and
- a transceiver configured to wirelessly transmit a message to the power transmitter in response to the received power,
- the power management circuit further configured to:
- determine that a power level of the received power has been adjusted in response to the message;
- initialize a controller in response to the determining, the controller configured to be powered at least in part by the adjusted power level.
An apparatus for performing the delay of an initialization sequence of a device, the apparatus comprising:
- means for controlling the device;
- means for detecting power wirelessly received from a power transmitter;
- means for wirelessly transmitting a message to the power transmitter in response to the received power;
- means for determining that a power level of the received power has been adjusted in response to the message;
- and
- means for initializing, in response to the determining, the controlling means, the controlling means configured to be powered by the adjusted power level.
A method of operating a wireless power receiver device, comprising:
- initializing an application processor based on a first initialization sequence of signals in response to detecting power received via a wired power source;
- and
- initializing the application processor based on a second initialization sequence of signals, different than the first initialization sequence of signals, in response to detecting power wirelessly received from a power transmitter, the second initialization sequence of signals based at least in part on a power level of the power wirelessly received from the transmitter.
