Abstract:
Systems, methods and/or devices are used to reduce anomalous charging current by selectively shunting biasing current away from a control terminal of a controlled device that conducts the charging current during a charging mode. In some embodiments, a power-control circuit includes: (1) a controlled device with a first terminal coupled to a power-supply node, a second terminal to provide a first output voltage, and a control terminal; (2) a current source to provide a biasing current to the control terminal of the controlled device during a charging mode; and (3) a selective current shunt to shunt a portion of the biasing current away from the control terminal of the controlled device in response to a determination that a charging current through the first and second terminals of the controlled device satisfies a threshold during the charging mode.
