ETA4116 16V/120mA, 1mA Termination Current Linear Charger DESCRIPTION ETA4116 is a single cell, fully integrated constant current (CC)/constant voltage (CV) Li-ion battery charger. Its compact package with minimum external components requirement makes the ETA4116 ideal for portable applications. No external sense resistor or blocking diode is necessary for the ETA4116. Build-in thermal feedback mechanism regulates the charge current to control the die temperature during high power operation or at elevated ambient temperature. The ETA4116 has a pre-charge function for trickle charging deeply discharged batteries. The fast charge current can be programmed by an external resistor.
