深圳市展嶸電子有限公司 有需要的上帝可聯(lián)系小陳，136-6225-3950 QQ：3412-1522-98 ETA9085，是鈺泰科技新出爐的超低功耗TWS充電倉芯片，帶4顆電量燈，也是全球首顆全集成超低功耗芯片。 ETA9085功能非常完善： 其特點如下：1、輸入耐壓高達20V，適應快充和PD市場高耐壓的要求；2、輸出5V常開，待機功耗小于10uA，真正的超低功耗；3、充電電流靈活可調(diào)，最大1A，適用各種電芯；4、帶EN使能控制，可以配合單片機做更多功能；5、常規(guī)4段電量顯示；6、帶充電NTC溫度保護，更加安全可靠；7、ESOP封裝簡單易貼，DFN小封裝節(jié)省空間，兩種封裝任選；8、輸入過壓、輸出過流、短路保護、電池過充過放保護，所有保護齊全。 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. In CV charge stage, charging will be terminated when the charge current drops to 1/10 of the programmed value. 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. Its 1.0MHz switching frequency enable a very small external inductor with inductance as low as 2.2uH. A fuel gauge also drives 4 LEDs for battery level indication. ETA9085 is ideal for applications such as a TWS charging cradle that requires low standby power and small PCB space. ETA9085 is housed in a ESSOP10 package
