Abstract
An adapter, a portable electronic device and a charge control method thereof are provided. The adapter includes a connector and a controller. The connector includes a first terminal. The controller is electrically connected to the connector and determines whether to enter a quick charge mode according to a control signal from the connector. In the quick charge mod, the controller receives a charge control signal from the first terminal. The charge control signal has a plurality of pulses, and encoding information is formed by the plurality of pulses. The adapter is controlled by the controller according to the encoding information so as to provide a quick charge voltage.
Claims23
An adapter, comprising:
- a connector, comprising a first terminal;
- and
- a controller, electrically connected to the connector, and determining whether to enter a quick charge mode according to a control signal from the connector,
- wherein in the quick charge mode, the controller receives a charge control signal from the first terminal, the charge control signal has a plurality of pulses, encoding information is formed by the plurality of pulses, and the controller controls the adapter according to the encoding information so as to provide a quick charge voltage.
A charge control method of an adapter, wherein the adapter comprises a connector, the charge control method of the adapter comprising:
- determining whether to enter a quick charge mode according to a control signal from the connector;
