ETA4084 - 16V/0.75A Fully Integrated Linear Charger

Description

ETA4084 is a fully integrated constant current (CC)/constant voltage (CV) charger for 2 cell Li-ion battery.

Its compact package with minimum external components requirement makes the ETA4084 ideal for portable applications.

No external sense resistor or blocking diode is necessary for the ETA4084.

Features

  • 16V standoff input voltage at VIN and BAT pins.
  • 8.4V charge termination voltage.
  • Charge current up to 750mA in SOT23-6 package.
  • No damage when battery reversely connected.
  • 25uA supply current when standby.
  • Soft-start limits in-rush current.
  • SOT23-6 package.

ETA4084 16V/0.75A Fully Integrated Linear Charger for 2 Cell Li-ion Battery DESCRIPTION ETA4084 is a fully integrated constant current (CC)/constant voltage (CV) charger for 2 cell Li-ion battery. Its compact package with minimum external components requirement makes the ETA4084 ideal for portable applications. No external sense resistor or blocking diode is necessary for the ETA4084. Build-in thermal feedback mechanism regulates the charge current to control the die temperature during high power operation or at elevated ambient temperature. The ETA4084 has a pre-charge function for trickle charging deeply discharged batteries. The fast charge current can be programmed by an external resistor.
