ETA9882 Datasheet | ETA

DESCRIPTION FEATURES ETA9882 is a switching Li-Ion battery charger capable of delivering up to 2.4A of charging current to the battery and also capable of delivering up to 2.4A in boost operation. ETA9882 includes a power path from IN to OUT, a buck charger, a 5V boost converter, and a charge status indication. The buck charger guarantees a 93.5% average efficiency at 2.4A charge current and the boost converter achieves 92% efficiency at 2.4A output when battery voltage is as low as 3.3V. It greatly increases the effective battery capacity for a battery powered system, such as power bank. With all these features , ETA9882 is an ideal allin-one solution for Li+ battery charging, discharging applications. - 20V Input Standoff Voltage - Bi-Directional Power Conversion with Single Inductor - Power Path from IN to OUT - ENBST and ENCHRG Function - 4.2V/4.35V Optional Battery CV voltage - Switching Charger - 5V Synchronous Boost - Up to 96% Efficiency - No External Sense Resistor - NTC Monitor - Charge Status Indication - Charge Current Programmable - Ro HS pliant APPLICATIONS ETA9882 is available in ESSOP10 package. - Power Bank - Li+ Battery Powered System TYPICAL APPLICATION Optional 10u F VIN ENBST ENCHRG VTERM 1 IN EP GND 3.3n F 22u Fx2 10u F VOUT 10 1Ω 3 ENBST SW 9 2.2u H 4 ENCHRG BAT 8 7 VTERM STAT 2 VOUT 2KΩ Li+ Battery 5...
