Abstract
A battery pack for use in a portable computing system includes a transistor that is used both for inhibiting charging of the batteries within the system and for limiting the voltage across the batteries in the battery pack. Rather than having two separate devices to inhibit and regulate, this single transistor performs the functions of both, thus reducing component count in a battery pack.
