ETA9085超低功耗5V升压转换器、为TWS充电架提供一体式解决方案

        ETA9085 is an all-in-one solution for TWS charge cradle. It includes a 20V single cell Li+ battery linear charger, a 5V Boost synchronous converter with true-shutoff function and a Fuel Gauge with LED indication. The linear charger is fully integrated with constant current (CC) / constant voltage (CV) control module and a charge FET. It has a pre-charge function for trickle charging a deeply discharged battery and its fast charge current can be programmed by an external resistor.
