ISL6294IBZ

Battery Chargers Overview

The ISL6294IBZ is a fully integrated high input voltage single-cell Li-ion battery charger manufactured by Renesas Electronics Corporation. It supports an input voltage up to 28V and utilizes a CC/CV charge profile. The device features 1% voltage accuracy, programmable charge current, and programmable end-of-charge current. It includes thermal foldback protection and trickle charging for deeply discharged batteries. The IC operates within an ambient temperature range of -40°C to +85°C and offers less than 1µA leakage current when disabled.

Battery Chargers Feature Summary

• Fully integrated charger with internal pass element and current sensor
• High input voltage tolerance up to 28V
• Programmable charge and end-of-charge currents via external resistors
• Internal thermal foldback for overtemperature protection

Battery Chargers Applications

• Mobile phones
• Bluetooth devices
• PDAs
• MP3 players
• Stand-alone chargers

Battery Chargers Procurement Notes

Verify the specific suffix 'IBZ' against official Renesas documentation to confirm package type (typically SOIC) and RoHS compliance status. Confirm component obsolescence status as the ISL6294 series is listed as obsolete in public records. Ensure compatibility with existing board layouts before procurement.

Battery Chargers Selection Notes

Select this component for single-cell Li-ion applications requiring high input voltage tolerance without external OVP circuits. It is suitable for designs prioritizing low component count and cost. Verify that the required charge current and EOC thresholds can be set using available external resistor values within the specified operating temperature range.

Battery Chargers Part Context

The ISL6294 belongs to the Renesas Intersil line of power management ICs designed for portable electronics. It replaces lower-input-voltage chargers by integrating overvoltage protection capabilities directly into the charger architecture. This integration reduces the overall bill of materials and simplifies the design process for mobile device manufacturers.

Battery Chargers Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. As the ISL6294 series is marked as obsolete, consult Renesas technical support or authorized distributors for current alternative recommendations.
