ISL9205IRZ-T

Battery Chargers Overview

The ISL9205IRZ-T is an integrated single-cell Li-ion or Li-polymer battery charger manufactured by Renesas Electronics Corporation. It supports input voltages from 2.5V to 6.5V and delivers a maximum programmable charge current of 900mA. The device implements standard CC/CV charging profiles with 15mV voltage accuracy at room temperature and 25mV over the operating range. It features Thermaguard thermal foldback protection, NTC interface capability, and less than 3μA leakage current. The component operates within an ambient temperature range of -40°C to +85°C and is housed in a 16-QFN (3x3) package.

Battery Chargers Feature Summary

• Integrates pass element and current sensor for low component count

• Supports trickle charging for fully discharged batteries
• Provides power presence and charge status indications

Battery Chargers Applications

• Single-cell Li-ion battery charging systems
• Li-polymer battery charging applications
• Portable electronic devices powered by AC adapters
• Low-voltage input charging solutions

Battery Chargers Procurement Notes

Verify the specific suffix against official documentation to confirm package type and tape/reel specifications. Confirm RoHS compliance status and moisture sensitivity level requirements prior to integration. Check for end-of-life notices as availability may be restricted. Ensure compatibility with existing PCB footprint and thermal management design constraints.

Battery Chargers Selection Notes

Select this component for designs requiring a compact, integrated solution for single-cell chemistry. Consider the 16-QFN package for space-constrained layouts. Evaluate the need for NTC monitoring based on package availability. Verify that the input source characteristics align with the linear or pulse charging modes supported by the IC.

Battery Chargers Part Context

This part belongs to the ISL9205 family of single-cell chargers, which includes variants like ISL9205A through D.
