Abstract

A circuit provides for regulating charge and discharge current of a battery. A bypass circuit is connected to a terminal of the battery and connected in parallel with a load switch. The bypass circuit may selectively direct a bypass current around the load switch. A controller can operate in plural modes to control the bypass circuit. In a first mode, the controller controls one or more parameters of the bypass current based on values corresponding to a current at the terminal, a voltage at the terminal, and/or a temperature of the battery. In a second mode, the controller controls the bypass circuit to disable the bypass current.
