Abstract
Apparatuses and methods for regulating a system rail voltage of a battery charger is described. An integrated circuit can be configured to detect a condition that requires an activation of a trickle charge mode of a battery charger. The integrated circuit can, in response to the detection, set a reference voltage to an intermediate voltage level. The reference voltage can control a system rail voltage of the battery charger, and the intermediate voltage level can be greater than a minimum of the system rail voltage. The integrated circuit can reduce the reference voltage from the intermediate voltage level to the minimum system rail voltage to regulate the system rail voltage at a predefined rate.
