Automatic Detection of USB Port vs. Wall Adapter Power
The AAT3685 is a versatile Lithium-ion/polymer (Li-ion/poly) battery charge control IC capable of charging single-
cell Li-ion/poly batteries at constant current rates up to 1A. The AAT3685 also utilizes an automatic charge reduc-
tion technique, allowing the device to safely operate from USB port power sources for charging batteries. In addi-
tion, this unique charger IC has the capability to be programmed for two discrete constant current charge levels.
Collectively, these features make the AAT3685 an ideal solution for portable product applications which utilize
both an AC wall adapter and a USB port for a charge source supply through a single input power connector.
