Intersil ISL9203ACRZ

锂离子1.5A-20°C ~ 70°C（TA）

Overview

The ISL9203ACRZ 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 ISL9203ACRZ operates as a linear charger when the AC adapter is a voltage source. The battery is charged in a Constant Current/Constant Voltage (CC/CV) profile. The charge current is programmable with an external resistor up to 1.5A. The ISL9203ACRZ can also work with a current-limited adapter to minimize the thermal dissipation, in which case the ISL9203ACRZ combines the benefits of both a linear charger and a pulse charger.

The ISL9203ACRZ features charge current thermal foldback to ensure safe operation when the Printed Circuit Board (PCB) is space limited for thermal dissipation. Additional features include preconditioning of an over-discharged battery and thermally enhanced DFN package.
