ETA钰泰 ETA4064S2F 单节锂电池充电IC

DESCRIPTION

ETA4060 is a single cell, flly integrated constant current (CC)constant woltage (CV) L-ion battery charger. lts compact package with minimum extemal oomponents requirement makes the ETA4060 ideal for portable appliations. No extemal 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 curent can be programmed by an extemal resistor. CV regulation mode is automatically enabled once the battery's charging curve reaches the constant voltage portion. The pre-charge current and the temination current threshold are programmed by an extemal resistor as well. The ETA4060 keeps monitoring the battery voltage and enables a new charge cycle once the voltage drops by 100mV below theCV value.

ETA4060 is in a DFN2X2-10 package.
