ETA40563 Datasheet | ETA

DESCRIPTION FEATURES ETA40563 is a single cell, fully integrated constant current (CC)/constant voltage (CV) Li-ion battery charger. Its pact package with minimum external ponents requirement makes the ETA40563 ideal for portable applications. No external sense resistor or blocking diode is necessary for the ETA40563. Build-in thermal feedback mechanism regulates the charge current to control the die temperature during high power operation or at elevated ambient temperature. The ETA40563 has a pre-charge function for trickle charging deeply discharged batteries. 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 1/10th of the programmed value. The ETA40563 keeps monitoring the battery voltage and enables a new charge cycle once the voltage drops by 120m V below the CV value. ETA40563 is in a DFN2x2-8 package. - 16V Input Standoff Voltage - 4.35V Charge Termination Voltage - 2.93V Trickle Charge Threshold - Charge Current Programmable, Up to 1.2A - 250n A BAT Current when No Charging - Soft-start Limits in-rush Current - DFN2x2-8 Package - Ro HS pliant APPLICATIONS - E-cigarette - Toys - Bluetooth applications - Li-ion battery powered devices TYPICAL APPLICATION 1K 4.7u F 1 VIN BAT 8 3 STAT ETA40563 NTC 6 2 STDBY 4 EN ISET 7 GND R1 RNTC Li+ Battery RISET VBAT/VSYS 1u F ORDERING INFORMATION PART No. ETA40563D2I PACKAGE DFN2x2-8 TOP MARK...
