Battery Chargers datasheet and documents for ISL95521AIRZ

ISL95521AIRZ

Battery Chargers Overview

The ISL95521AIRZ is a combo battery charger supporting 2 to 4-cell Li-ion or Li-polymer batteries. It operates in Hybrid Power Boost (HPB) or Narrow VDC (NVDC) configurations, enabling Turbo mode where the battery supplements the adapter during high system loads. The device utilizes N-channel MOSFETs for all switches and features an internal charge pump for rapid gate driving. It includes SMBus programmability, hardware-based current limits, and comprehensive protection against overcurrent and overheating.

Battery Chargers Feature Summary

Configurable as HPB or NVDC charger with Turbo mode support
Uses NFETs for all switches to optimize performance and cost
SMBus programmable settings with high accuracy monitoring
Comprehensive protection including PROCHOT# indicators

Battery Chargers Applications

Hybrid Power Boost battery charging systems
Narrow VDC battery charging applications
Systems requiring simultaneous adapter and battery power supply
Turbo mode operation for high-load scenarios
