Abstract
Techniques are provided for selecting a charge current to be sunk by a mobile electronic device. A charging device is received at a connector of the mobile electronic device. The charging device is configured to supply a charge current to a rechargeable battery of the mobile electronic device. One or more data signals is/are received from the charging device at an interface circuit of the mobile electronic device on one or more data signal lines through the connector. One or more control signals are applied to the interface circuit to enable data signal values to be generated for the data signal(s) based on the control signal(s) and a type of the charging device. The data signal values are mapped to a maximum charge current for the rechargeable battery. The charge current supplied by the charging device to the rechargeable battery is limited to the selected maximum charge current.
