描述 Description

The AAT3682 is a lithium-ion/polymer linear battery charger. It is designed for compact portable applications with a single cell battery. The AAT3682 precisely regulates battery charge voltage and charge current, and offers an integrated pass device, minimizing the number of external components required.
The AAT3682 charges the battery in three different phases: preconditioning, constant current, and constant voltage. In preconditioning mode, the charge current has two different levels and is controlled by one external pin. Battery charge temperature and charge state are carefully monitored for fault conditions. A battery charge stable monitor output pin is provided to indicate the battery charge status through a display LED or interface to a system controller. The AAT3682 has the sleep mode option for when the input supply is removed. In this mode, it draws only 2.0µA of typical current.
The AAT3682 is available in a 16-pin QFN44 and is specified over the -20°C to +70°C temperature range.
