ETA4042 30V Input Standoff, 1A Fully Integrated Linear Charger for 1 Cell Li-ion Battery DESCRIPTION FEATURES ETA4042 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 ETA4042 ideal for portable applications. No external sense resistor or blocking diode is necessary for the ETA4042. Build-in thermal feedback mechanism regulates the charge current to control the die temperature during high power operation or at elevated ambient temperature. The ETA4042 has the function of precharge, which can charge the deeply discharged batteries by trickle. The fast charge current can be programmed by an external resistor.
