ISL9216IRZ-T

Battery Management Overview

The ISL9216IRZ-T is a battery protection integrated circuit designed for single-cell lithium-ion and lithium-polymer batteries. It operates within a supply voltage range of 2.0V to 24V and supports continuous load currents up to 3A. The device features low on-resistance switches and provides comprehensive protection against over-voltage, under-voltage, over-current, and short-circuit conditions. It is housed in a compact 32-QFN package with dimensions of 5x5mm, suitable for space-constrained portable electronics.

Battery Management Feature Summary

• Integrated dual N-channel MOSFETs for charge and discharge control
• Programmable current limit and delay times via external resistors
• Automatic recharge function upon recovery from undervoltage lockout

Battery Management Applications

• Portable consumer electronics such as smartphones and tablets
• Power tool battery packs requiring high current protection
• Medical devices needing reliable single-cell battery management

Battery Management Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging rather than tube. Confirm the manufacturer part number matches Renesas Electronics Corporation specifications. Check RoHS compliance status and moisture sensitivity level before integration into production lines.

Battery Management Selection Notes

Select this component when designing circuits requiring robust overcurrent protection for single-cell Li-ion applications. Ensure the external programming resistors align with the desired trip points and delay times specified in the datasheet. Consider thermal performance given the 3A continuous current capability in the QFN-32 package.
