AAT3684 | 500mA USB Port Or AC Adapter Lithium-Ion/Polymer Battery Charger

The AAT3684 BatteryManager is an integrated single cell lithium-ion/polymer Battery Charger IC, designed to operate from a DC power source or USB port up to an input voltage of 6.5V. It requires just one external component. The AAT3684 precisely regulates battery charge voltage and current for 4.2V (4.375V option) lithium-ion/polymer battery cells. When charged from an AC adapter or USB port, the battery charging current CAN be set by an external resistor up to 500mA. Battery charge state is continuously monitored for fault conditions. In the event of an over-voltage, short-circuit, or over-temperature failure, the device will automatically shut down, thus protecting the charging device, control system, and the battery under charge. A status monitor output pin is provided to indicate the battery charge status by directly driving an external LED The AAT3684 is available in a Pb-free, thermally enhanced, space-saving 10-pin 2.2x2.2mm STDFN package and is specified for operation over the -40C to +85C temperature range.
