钰泰单电感器 ETA6884Q43 3A电池充电IC

DESCRIPTION

ETA6884 is a switching Lilon battery charger capable of delivering up to 3A of charging current to the battery and also capable of deliering up to 2.4A in boost IG operation. It employs a charge pump to achieve a very fast input 0VP, and also includes an externally programmable fuel gauge system for power indication. For charging, it uses a proprietary control scheme that eliminates the current sense resistor for constant current control, thereby improving efficiency and reducing costs. It can also output a 5V voltage in the reversed direction by boosting from the battery. Therefore, it only needs a single inductor to provide power bidirectionally.Together with the build-in Micro-controller functions. such as push-button, auto load detection, and fuel gauging features.

ETA6884 is truly an ideal al-in-one solution for battery charging and discharge applications, such as power banks, smart phones, and tablets with only one USB port that can be used for both charging battery and USB function.
