The AAT3670ISK-4.2-T1 from Skyworks Solutions is a BatteryManager IC designed for single-cell lithium-ion/polymer batteries. This highly integrated device manages both battery charging and system power, allowing for simultaneous charging and operation without compromising battery life.
It supports low-voltage AC adapter (ADP) and USB inputs, requiring minimal external components. The IC precisely regulates battery charge voltage to 4.2V and current, which can be programmed up to 1.6A for ADP charging and up to 0.9A for USB charging. A voltage-sensed charge current reduction loop ensures system operation even when input voltage fluctuates.
Key features include fault protection for over-current, over-temperature, over-voltage, and short circuits. Status monitor output pins (STAT1 and STAT2) are provided for indicating battery charge status. The device operates within a temperature range of -40°C to 85°C.
Packaged in a space-saving 24-pin 4x4mm QFN, the AAT3670ISK-4.2-T1 is suitable for various portable electronic devices such as cellular telephones, digital cameras, PDAs, and MP3 players.
