Abstract: In some examples, a shunt regulator includes a plurality of selection pins configured to receive a digital signal. The shunt regulator also includes an internal reference voltage selection circuit coupled to the plurality of selection pins, the internal reference voltage selection circuit configured to select a first internal reference voltage of the shunt regulator based on the digital signal. The shunt regulator further includes a soft ramp control circuit coupled to the internal reference voltage selection circuit and to a soft ramp control pin that is configured to carry a second internal reference voltage, the soft ramp control circuit configured to compare the first and the second internal reference voltages to generate a soft ramp control output signal.

Abstract: Described examples include a system having a power source having a first output terminal and a second output terminal and a controller. The system also has a selective charger coupled to the controller, the selective charger configured to couple, in response to instructions from the controller, the first output terminal of the power source to a first node that is configured to be coupled to a first terminal of a selected battery cell of two or more serially coupled battery cells, and couple the second output terminal of the power source to a second node configured to be coupled to a second battery terminal of the selected battery cell.
