ETA9084D3K电池充电管理芯片
DESCRIPTION
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.
The ETA9084 is ideal for applications such as a TWS
charging cradle that requires low standby power and
small PCB space.
The ETA9084 is housed in a ESSOP10/DFN3x3-10
