1.2A/40V Fully Integrated Linear Charger for 1 Cell Li-ion Battery DESCRIPTION ETA4255 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 ETA4255 ideal for portable applications. No external sense resistor or blocking diode is necessary for the ETA4255. Build-in thermal feedback mechanism regulates the charge current to control the die temperature during high power operation or at elevated ambient temperature. The ETA4255 has a pre-charge function for trickle charging deeply discharged batteries. The fast charge current can be programmed by an external...
