1.2A/16V Fully Integrated Linear Charger for 1 Cell Li-ion Battery

DESCRIPTION

FEATURES

ETA40563 is a single cell, fully integrated constant current

16V Input Standoff Voltage

(CC)/constant voltage (CV) Li-ion battery charger. Its compact  4.35V Charge Termination Voltage

makes the ETA40563 ideal for portable applications. No  Charge Current Programmable, Up to 1.2A

external sense resistor or blocking diode is necessary for the  250nA BAT Current when No Charging

power operation or at elevated ambient temperature. The  RoHS Compliant

ETA40563 has a pre-charge function for trickle charging

deeply discharged batteries. The fast charge current can be

programmed by an external resistor. CV regulation mode is

automatically enabled once the battery’s charging curve

APPLICATIONS

reaches the constant voltage portion. The output current then

decays and is finally terminated once the charge current drops

to 1/10th of the programmed value. The ETA40563 keeps

monitoring the battery voltage and enables a new charge

cycle once the voltage drops by 120mV below the CV value.

ETA40563 is in a DFN2x2-8 package.
