Abstract
A battery charger circuit includes a transistor having a first current electrode for receiving a charging voltage, a control electrode for receiving a control signal, and a second current electrode for providing an output voltage. The battery charger circuit further includes a rectifier having a terminal coupled to the second current electrode of the transistor, and another terminal coupled to a power supply voltage terminal. The battery charger circuit also includes a control and regulation circuit having an input for receiving a feedback signal representative of a temperature, and an output for providing the control signal. The control and regulation circuit operates in either a switching mode or a linear mode in response to the feedback signal.
