ISL9203 Datasheet Li-ion/li Polymer Battery Charger

Manufacturer: Intersil (now Renesas)

Overview: .. ® ISL9203 Data Sheet February 3, 2005 FN6106.0 Li-ion/Li Polymer Battery Charger The ISL9203 is an integrated single-cell Li-ion or Li-polymer battery charger capable of operating with an input voltage as low as 2.4V. This charger is designed to work with various types of ac adapters. The ISL9203 operates as a linear charger when the ac adapter is a voltage source. The battery is charged in a CC/CV (constant current/constant voltage) profile. The charge current is programmable with an external resistor up to 1.5A. The ISL9203 can also work with a current-limited adapter to minimize the thermal dissipation, in which case the ISL9203 bines the benefits of both a linear charger and a pulse charger.

Key Features

  • charge current thermal foldback to guarantee safe operation when the printed circuit board is space limited for thermal dissipation. Additional features include preconditioning of an over-discharged battery, automatic recharge, and thermally enhanced DFN package. Features.
  • Pb-Free Available (RoHS Compliant).
  • Complete Charger for Single-Cell Li-ion Batteries.
  • Very Low Thermal Dissipation.
  • Integrated Pass Element and Current Sensor.
  • No External Blockin.
