A method for charging a battery of an electronic device using a connected a/c power adapter comprising the steps of determining a state of a transistor connecting a regulated voltage to the battery and switching a charging current applied to the battery between a quick charge level and a trickle charge level responsive to the state of the transistor.

System and method of trickle charging a battery in a narrow rail architecture

The charging circuit for charging a battery of an electronic device using a connected AC power adaptor includes circuitry responsive to an applied regulated voltage for charging the battery connected to the charging circuitry. The circuitry prevents the regulated voltage applied to the circuitry from falling below a settable voltage level. Additionally, the circuitry switches a charging current between a quick charge level and a trickle charge level responsive to a state of a transistor.
