BQ7721610PWR

Battery Management Overview

The BQ7721610PWR is a battery protection integrated circuit designed for lithium-ion battery packs. It operates within a supply voltage range of 5 V to 75 V and supports configurations for 3 to 16 series cells. The device provides comprehensive fault protection, including overvoltage, undervoltage, and overtemperature detection. It features a low operating supply current of 2 uA and functions reliably across an extended temperature range from -40°C to +110°C. The component is housed in a 24-TSSOP package with a width of 4.40 mm.

Battery Management Feature Summary

• Provides hardware-based protection against cell overvoltage, undervoltage, and pack-level faults.
• Integrates overtemperature sensing to prevent thermal runaway conditions.
• Supports high-voltage battery architectures up to 75 V system voltage.

Battery Management Applications

• Protection circuits for portable electronic devices
• Battery management systems for power tools
• Uninterruptible power supply (UPS) battery packs

Battery Management Procurement Notes

Verify the specific suffix PWR confirms the TSSOP-24 package and lead-free status. Confirm RoHS compliance details via the manufacturer datasheet. Ensure the ordering part number matches the required cell count configuration. Check humidity sensitivity level requirements for surface mount assembly processes.

Battery Management Selection Notes

Select this component when designing protection for lithium-ion packs requiring 3 to 16 series cells. Ensure the system voltage does not exceed 75 V. Verify that the 24-TSSOP footprint fits the PCB layout constraints. Consider the 2 uA quiescent current for low-power standby applications.

Battery Management Part Context

This part belongs to the BQ77216 family of battery protection ICs from Texas Instruments. It shares core protection logic with variants like BQ7721609PWR and BQ7721613PWR, differing primarily in internal threshold settings or pin configurations. These components are categorized under PMIC battery protection solutions.

Battery Management Replacement Considerations

Direct substitutes include BQ7721609PWR and BQ7721613PWR. Verify functional equivalence regarding protection thresholds and pin compatibility before substitution. Consult official documentation for any differences in electrical characteristics or package markings.
