DESCRIPTION
ETA9185 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 1.0A 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 allows a very
small external inductor with inductance as low as
2.2uH. A fuel gauge also drives 4 LEDs for battery
level indication. ETA9185 is ideal for applications
such as a TWS charging cradle that requires low
standby power and small PCB space.
ETA9185 is housed in a ESSOP10/DFN3x3-10
package
