General Description

The LT®3651 is a 4A Li-Ion/Polymer battery charger that operates over a 4.8V to 32V input voltage range.

An efficient monolithic average current mode synchronous switching regulator provides constant current, constant voltage charging with programmable maximum charge current.

A charging cycle starts with battery insertion or when the battery voltage drops 2.5% below the float voltage.
