ETA ETA40561
ETA40561 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 ETA40561 ideal for portable applications. The ETA40561 has the function of pre-charge, which can charge the deeply discharged batteries by trickle.| Part No. | ETA40561 |

DESCRIPTION
No external sense resistor or blocking diode is necessary for the ETA40561. Build-in thermal feedback mechanism regulates the charge current to control the die temperature during high power operation or at elevated ambient temperature. The fast charge current can be programmed by an external resistor. CV regulation mode is automatically enabled once the battery’s charging curve reaches the constant voltage portion. The output current then decays and is finally terminated once the charge current drops to 1/10 of the programmed value. The ETA40561 keeps monitoring the battery voltage and enables a new charge cycle once the voltage drops by 120mV below the CV value. ETA40561 is available in an ESOP8 package.FEATURES
