Abstract

See full text

A linear charger circuit and method for providing an output current at an output node is presented. The circuit contains a pass device connected between an input node and the output node, first and second replica devices connected in parallel to the pass device, with their control terminals coupled to a control terminal of the pass device. The first replica device is coupled to a first circuit path for determining whether current output by the linear charger circuit shall be terminated. The second replica device is coupled to a second circuit path for providing feedback for controlling the pass device, a control circuit coupled to the second circuit path for controlling the pass device based on a quantity indicative of a current flowing through the second circuit path, and a switching circuit coupled to the second circuit path.
