BQ76925PW

Battery Management Overview

The BQ76925PW is a battery management analog front-end (AFE) designed for 3 to 6 series lithium-ion or lithium-polymer cells. It operates within a supply voltage range of 4.2 V to 26.4 V and features a low quiescent current of 40 uA. The device is housed in a TSSOP-20 package suitable for surface mount installation. It supports an operating temperature range from -25°C to +85°C and includes humidity sensitivity classification.

Battery Management Feature Summary

• Integrated protection and monitoring for multi-cell lithium-based battery stacks
• Low power consumption architecture with minimal quiescent current draw
• Supports standard surface-mount assembly processes

Battery Management Applications

• Battery management systems for portable electronics
• Power tool battery packs
• Medical equipment battery modules
• Uninterruptible power supply (UPS) systems

Battery Management Procurement Notes

Verify the specific suffix 'PW' confirms the TSSOP-20 package variant when sourcing. Ensure compatibility with the intended PCB footprint and thermal requirements. Confirm RoHS compliance status through official manufacturer documentation prior to integration into regulated products.

Battery Management Selection Notes

Select this component for applications requiring integrated cell balancing and protection for up to six series cells. Consider the TSSOP-20 package constraints regarding board space and thermal dissipation. Evaluate the -25°C to +85°C operating range against environmental conditions.

Battery Management Part Context

This part belongs to the BQ76925 family of battery monitors. It serves as a core analog front-end for managing high-voltage battery strings. The PW suffix specifically denotes the plastic small-outline package type, distinguishing it from other form factors like the RGER variant.

Battery Management Replacement Considerations

Consult official Texas Instruments documentation for verified cross-reference part numbers. Do not assume functional equivalence with other battery AFEs without validating pinout and electrical specifications.
