ETA4054 16V/1A Fully Integrated Linear Charger for 1 Cell Li-ion Battery DESCRIPTION ETA4054 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 ETA4054 ideal for portable applications. No external sense resistor or blocking diode is necessary for the ETA4054. Build-in thermal feedback mechanism regulates the charge current to control the die temperature during high power operation or at elevated ambient temperature. The ETA4054 has a pre-charge function for trickle charging deeply discharged batteries. The fast charge current can be programmed by an external resistor.
