The ACT2800 family was architected to integrate the complete Power Bank functionality into one system-on-a-chip. Power Bank chipsets on the market today require multiple ICs, such as micro controller units (MCUs), to perform the charging and battery management functions in addition to several discrete components. The ACT2800 family reduces the system footprint and minimizes design complexity, while leaving room for larger batteries and reducing total system cost.
The ACT2801 device supports output current up to 1.5A while the ACT2802 supports output current up to 2.1A to reduce charging time when using larger batteries. The chips feature 95% of power conversion efficiency, a low battery leakage current of under 10uA, programmable current limiting, and protection features such as over-temperature protection, over-current protection, over-voltage protection, and short-circuit protection. Also integrated are a push-button user input and signal for a LED based “power meter” for battery level indication.
