ETA4060D2K 钰泰1A线性充电器 30V输入电压

　　DESCRIPTION

　　ETA4060 is a single cell, fully integrated constant current (CC)/constant voltage (CV) Li-ion battery charger. lts compact package with minimum external components requirement makes the ETA4060 ideal for portable applications. No external sense resistor or blocking diode is necessary for the ETA4060. Build-in thermal feedback mechanism regulates the charge current to control the die temperature during high power operation or at elevated ambient temperature.The ETA4060 has the function of pre-charge,which can charge the deeply discharged batteries by trickle. 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 pre-charge current and the termination current threshold are programmed by an external resistor as well.The ETA4060 keeps monitoring the battery voltage and enables a new charge cycle once the voltage drops by 100mV below the CV value.
