AAT3681AIJS-4.2-4-T1 Description

Short technical summary and product information.

The AAT3681AIJS-4.2-4-T1 from Skyworks Solutions is an integrated single-cell lithium-ion/polymer battery charger IC. It is designed to operate from a DC power source or USB port with an input voltage range of 4.0V to 7.5V. The device precisely regulates battery charge voltage and current for 4.2V lithium-ion/polymer battery cells.

 

This charger IC features a programmable charge current from 15mA to 500mA, set by an external resistor. It includes automatic current sensing, recharge sequencing, and full battery charge auto turn-off. For fault conditions such as over-voltage, short-circuit, or over-temperature, the device automatically shuts down, protecting the system and battery. A status monitor output pin is provided to directly drive an external LED indicating charge status.

 

The AAT3681AIJS-4.2-4-T1 is available in a Pb-free, thermally enhanced, 8-pin 2.0 × 2.0mm SC70JW package. It is specified for operation over the -40°C to +85°C temperature range. This component is suitable for various battery-powered devices including Bluetooth headsets, digital cameras, MP3 players, and PDAs.
