Battery Chargers datasheet and documents for ISL95521BIRZ

ISL95521BIRZ

Battery Chargers Overview

The ISL95521BIRZ is a combo battery charger IC from Renesas Electronics, supporting 2 to 4-cell Lithium-ion or Polymer batteries. It operates within a supply voltage range of 4.75V to 25V and features I2C and SMBus interfaces for programmable control. The device is housed in a 32-VFQFN package with exposed pad (4x4mm) and supports surface mount installation. It functions as either a Hybrid Power Boost (HPB) or Narrow VDC (NVDC) charger, utilizing N-channel MOSFETs for all switches.

Battery Chargers Feature Summary

Configurable operation as Hybrid Power Boost (HPB) or Narrow VDC (NVDC) charger
Supports system Turbo mode where battery assists adapter during high load conditions
Utilizes N-channel MOSFETs for all internal switches to optimize performance and cost
Includes hardware-based current limits and comprehensive protection features

Battery Chargers Applications

Notebook computer battery charging systems
Portable electronic devices requiring 2-4 cell Li-ion/Polymer support
Systems requiring Intel PROCHOT# compliance
Hybrid power boost applications

Battery Chargers Procurement Notes

Verify the specific suffix 'IRZ' indicates tube packaging rather than tape and reel. Confirm that the component meets RoHS3 standards and check Moisture Sensitivity Level (MSL) classification for handling requirements. Ensure compatibility with SMBus/I2C protocols used in the target design before finalizing procurement.

Battery Chargers Selection Notes

Select this model when both HPB and NVDC operational modes are required for flexibility. It is suitable for designs needing precise current monitoring via SMBus and hardware limits. Consider the 32-QFN package size constraints and thermal dissipation capabilities relative to the application's power density requirements.

Battery Chargers Part Context

The ISL95521 series includes variants like ISL95521AHRZ and ISL95521BHRZ. The ISL95521BIRZ specifically denotes the tube-packaged version of the B-grade variant. It shares core functionality with other ISL95521 models but differs in packaging and potentially minor manufacturing revisions.
