ETA42564 1.2A/40V Fully Integrated Linear Charger for 1 Cell Li-ion Battery DESCRIPTION ETA42564 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 ETA42564 ideal for portable applications. No external sense resistor or blocking diode is necessary for the ETA42564. Buildin thermal feedback mechanism regulates the charge current to control the die temperature during high power operation or at elevated ambient temperature. The ETA42564 has a pre-charge function for trickle charging deeply discharged batteries. The fast charge current can be programmed by an external resistor.
