0A USB Port/Adapter Lithium-Ion/Polymer Battery Charger General Description The AAT3689 BatteryManager is a highly integrated single cell lithium-ion/polymer battery charger IC designed to operate with USB port and AC adapter inputs.
It requires a minimum number of external components.
The AAT3689 precisely regulates battery charge voltage and current for 4.
2V lithium-ion/polymer battery cells.
Adapter charge current rates may be programmed up to 1.
0A.
In the absence of an adapter and with a USB port connected, the battery can also be charged by USB power.
The USB charge current can be programmed up to 500mA.
USB charging is disabled when an adapter is present.
AAT3689 Features • • • • BatteryManager™ Battery temperature and charge state are fully monitored for fault conditions.
In the event of an over-voltage or over-temperature failure, the device will automatically shut down, thus protecting the charging device, control system, and the battery under charge.
Status monitor output pins are provided to indicate the battery charge status by Applications directly driving two external LEDs.
