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
