ETA4060 Datasheet | ETA

DESCRIPTION FEATURES ETA4060 is a single cell, fully integrated constant current (CC)/constant voltage (CV) Li-ion battery charger. Its pact package with minimum external ponents requirement makes the ETA4060 ideal for portable applications. No external sense resistor or blocking diode is necessary for the ETA4060. Build-in thermal feedback mechanism regulates the charge current to control the die temperature during high power operation or at elevated ambient temperature. The ETA4060 has the function of pre-charge, which can charge the deeply discharged batteries by trickle. The fast charge current can be programmed by an external resistor. CV regulation mode is automatically enabled once the battery’s charging curve reaches the constant voltage portion. The pre-charge current and the termination current threshold are programmed by an external resistor as well. The ETA4060 keeps monitoring the battery voltage and enables a new charge cycle once the voltage drops by 100m V below the CV value. ETA4060 is in a DFN2X2-10 package. - 30V Input Standoff Voltage - 4.4V Charge Termination Voltage - Charge Current Programmable, Up to 1A - Pin Selectable USB 100m A or 500m A Maximum Input Current Limit - Programmable Termination Current and Pre- charge Current Threshold - Operation over JEITA Range via Battery NTC - Fixed 10 hours Safety Timer - Soft-start Limits in-rush Current - DFN2X2-10 Package APPLICATIONS - E-cigarette - Toys - Wearable Devices - Li-ion Battery Powered Devices TYPICAL APPLICATION 4.7u F Option al C ISET 1.5K 1.5K 1 VIN ISET2 7 5 n PG ETA4060 8 n CHG BAT 10 R ISET R PRET ER M 2 ISET 4 PRETERM GND 3 TS 9 High: Input current limit =500m A Float: Input current limit=100m A Low: Input current limit=ISET System Load Li + Batt ery 2.2u F ORDERING INFORMATION PART No. ETA4060D2K PACKAGE TOP MARK Pcs/Reel DFN2X2-10 Bz...
