为TWS充电架提供一体式解决方案ETA9084E10

        The ETA9084 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. The integrated low power 5V Boost converter is capable of delivering 0.5A current at 5V output. It can be shut down by pulling the  ENBST pin low. The true shut down feature disconnect output from the BAT thereby further decreasing the system standby power. There are 4 LEDs driven by 3 output pins to indicate the charge/discharge status and battery level.
