Abstract
A method, apparatus and non-transitory computer-readable medium of regulating current within a battery charging circuit. The apparatus including a first current sense resistor configured to sense a first current value at a first port, a second current sensor resistor configured to sense a battery discharge current value output from a battery, and a processor configured to, in response to a short circuit or malfunction at the first current sense resistor, use the battery discharge current value to determine an output current limit and to limit the current at the first port according to the output current limit.
