ETA4256 1.2A/40V Fully Integrated Linear Charger for 1 Cell Li-ion Battery DESCRIPTION ETA4256 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 ETA4256 ideal for portable applications. No external sense resistor or blocking diode is necessary for the ETA4256. Build-in thermal feedback mechanism regulates the charge current to control the die temperature during high power operation or at elevated ambient temperature. The ETA4256 has a pre-charge function for trickle charging deeply discharged batteries. The fast charge current can be programmed by an external resistor.
