ETA4048 30V Input Standoff, 1A Fully Integrated Linear Charger for 1 Cell Li-ion Battery DESCRIPTION ETA4048 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 ETA4048 ideal for portable applications. No external sense resistor or blocking diode is necessary for the ETA4048. Build-in thermal feedback mechanism regulates the charge current to control the die temperature during high power operation or at elevated ambient temperature. The ETA4048 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.
