BQ294532DRVR

Battery Management Overview

The BQ294532DRVR is a battery protection integrated circuit designed for lithium-ion and lithium-polymer batteries. It provides overvoltage protection specifically for 2 to 3 cell configurations. The device operates within a supply voltage range of 3 V to 25 V and features a low operating supply current of 1 uA. It delivers an output voltage of 4.5 V with an output current capability of 4.5 mA. The component is housed in a WSON-6 package, suitable for surface mount installation, and functions reliably across a temperature range of -40°C to +85°C.

Battery Management Feature Summary

• Provides dedicated overvoltage protection for multi-cell lithium-based battery packs
• Operates with ultra-low quiescent current to minimize standby power consumption
• Integrated fault protection mechanism safeguards against excessive cell voltage conditions

Battery Management Applications

• Protection circuits for 2-cell lithium-ion battery packs
• Protection circuits for 3-cell lithium-ion battery packs
• Lithium-polymer battery management systems requiring overvoltage monitoring

Battery Management Procurement Notes

Verify the specific suffix 'DRVR' corresponds to the standard tape-and-reel packaging configuration when ordering. Confirm that the application design accommodates the specified 3 V to 25 V operating voltage range. Ensure thermal management aligns with the +85°C maximum junction temperature rating. Cross-reference the datasheet for precise pinout definitions relative to the WSON-6 footprint to prevent assembly errors during integration.

Battery Management Selection Notes

Select this component when designing protection logic for 2 or 3 series connected lithium cells. The fixed 4.5 V output characteristic suits applications where a specific reference level is required. Consider the WSON-6 package size constraints for compact portable devices. Evaluate the 1 uA supply current impact on overall system battery life if continuous monitoring is active. Compare against other variants in the BQ2945xx family if different cell counts or voltage thresholds are needed.

Battery Management Part Context

This part belongs to the Texas Instruments BQ2945xx series of battery protection ICs. These devices focus on single-function overvoltage protection rather than comprehensive fuel gauge capabilities. The series supports various cell configurations through different model numbers, allowing designers to choose based on specific pack architecture requirements without redesigning the protection topology.

Battery Management Replacement Considerations

BQ294532DRVT is a verified alternative offering identical electrical specifications with a tray packaging option instead of reel.
