BQ7721615PWR

Battery Management Overview

The BQ7721615PWR is a battery protection IC from Texas Instruments designed for lithium-ion battery packs. It provides voltage and temperature protection for configurations ranging from 3-series to 16-series cells. The device operates within a supply voltage range of 5 V to 75 V and features high-accuracy overvoltage protection with tolerances of ±10 mV at 25°C and ±20 mV across the 0°C to 60°C temperature range. It is housed in a TSSOP-24 package.

Battery Management Feature Summary

• Independent cell monitoring for overvoltage, undervoltage, and open-wire conditions
• High-accuracy overvoltage protection capabilities
• Temperature protection support via external NTC thermistor integration

Battery Management Applications

• Lithium-ion battery pack protection
• Portable electronic devices requiring multi-cell battery management
• Power tools with series-connected lithium-ion batteries

Battery Management Procurement Notes

Verify the specific suffix 'PWR' confirms the TSSOP-24 surface-mount package type. Ensure compatibility with the target battery cell count (3 to 16 series) as defined by the BQ77216xx family specifications. Confirm RoHS compliance status through official manufacturer documentation before procurement.

Battery Management Selection Notes

Select this component when designing systems requiring independent cell monitoring for up to 16 series cells. The device is suitable for applications needing precise overvoltage detection within specified temperature ranges. Consider the TSSOP-24 footprint and 5 V to 75 V operating voltage window during PCB layout and system design.

Battery Management Part Context

This part belongs to the BQ77216 family of battery protection ICs from Texas Instruments.
