Overview

Lithium-Ion/Polymer Battery Charger General Description The AAT3687 BatteryManager is a highly integrated single-cell lithium-ion/polymer battery charger IC designed to operate with AC adapter inputs.
It requires a minimum number of external components.
The AAT3687 precisely regulates battery charge voltage and current for 4.
2V lithiumion/polymer battery cells.
Adapter charge current rates can be programmed up to 1.
5A.
An active thermal management system regulates the fast charge constant current for all ambient temperature and input vs.
output voltage conditions.
Battery temperature and charge state are fully monitored for fault conditions.
In the event of an over-voltage or over-temperatur...
