Shenzhen Zhanrong Electronics Co., Ltd. Liang Dong: 13923410857     QQ: 38839547 product description       Eta9697 is an ultra-low power PMU, It has two channels: a 16V single [url]] lithium battery linear charger and a 5V step-up synchronous converter with real off function.

Yutai eta9697 Bluetooth headset TWS charging box high voltage input 20V, 5V normally open, ultra low power consumption 1uA

the linear charger is fully integrated with constant current CC / constant voltage (CV) control module and charging FET.
it has * small external devices.
it also has pre charging function for deep discharge battery trickle charging.
its fast charging current can be adjusted It is programmed by an external resistor.
when entering the CV charging phase.
once the charging current drops to 1 / 10 of the programmed value, the charging will be terminated.
a "stat" pin can also be used to indicate the charging state.
the low-power 5V boost converter can provide 0.4 a current at 5V output.
it can be turned off by pulling enbst down.
it will turn off the bat output, The eta9697 is an ideal system solution, which requires a very low standby power supply and compact [url] PCB size.
eta9697 is packaged as esop8.
product feature 1 Low standby power consumption quotient.
