Abstract
It is an object of one or more embodiments of the present disclosure to provide a battery charger with a constant current control loop, for use in linear and switching chargers. Advantages include digital controls and a comparator, for decreasing charging current towards termination. The technique of the disclosure eliminates a constant voltage loop and amplifier, without increasing charging time. The technique also simplifies porting the design to another process technology node, and reduces size.
