Abstract: In one embodiment, a digital internal amplified voltage of power management circuitry is forced to an input threshold voltage upon a determination that a set of emergency conditions is satisfied, and is set to an input minimum battery voltage upon a determination that the set of emergency conditions is not satisfied. The emergency conditions may include determining that a battery voltage is less than a threshold voltage and determining that an input minimum battery voltage is less than an input threshold voltage.
