AAT3698 Description

The AAT3698-1/-2 BatteryManager™ is a single-cell lithium-ion (Li-Ion)/Li-Polymer battery charger IC designed to operate from a USB port or AC adapter with an input voltage of up to 7.0V. For increased safety, the AAT36981/-2 also includes over-voltage input protection (OVP) up to 28V. The AAT3698-1/-2 precisely regulates battery voltage for 4.2V Li-Ion/Polymer battery cells through a low RDS(ON) switch.
