ISL9219IRZ-TR5332

Battery Chargers Overview

The ISL9219IRZ-TR5332 is a fully integrated single-cell Li-ion battery charger from Intersil, compliant with USB electrical specifications. It supports input voltages up to 28V and features an overvoltage protection threshold typically at 6V. The device executes standard CC/CV charging profiles with a fixed end-of-charge current of 50mA. Key electrical parameters include a typical suspend quiescent current of 250µA and leakage current of less than 1µA when off. Operating temperature range is -40°C to +85°C.

Battery Chargers Feature Summary

• Fully integrated high input voltage capability up to 28V
• USB specification compliance for 100mA and 500mA sources
• Integrated overvoltage protection preventing excessive power dissipation

Battery Chargers Applications

• Single-cell Lithium-ion battery charging in portable devices
• USB-powered consumer electronics applications
• Low-voltage battery management systems requiring high input tolerance

Battery Chargers Procurement Notes

Verify the specific suffix TR5332 against official Renesas/Intersil documentation to confirm packaging and material specifications. Ensure compatibility with moisture-sensitive handling protocols as indicated by component data sheets. Cross-reference part numbers with current manufacturer catalogs to confirm active status and availability constraints.

Battery Chargers Selection Notes

Select this component for applications requiring high input voltage tolerance without external OVP circuits. Consider the fixed 50mA termination current for system design. Evaluate thermal performance within the specified operating temperature range. Confirm package requirements match the 20-QFN exposed pad configuration.

Battery Chargers Part Context
