BQ29702DSET

Battery Management Overview

The BQ29702DSET is a single-cell battery protection IC from the BQ2970 family, designed for Lithium-ion and Lithium Polymer batteries. It operates within a supply voltage range of up to 8 V and features a low quiescent current of 4 uA. The device provides overvoltage protection with a threshold of 4.35 V. Packaged in a compact 6-WSON (1.5x1.5 mm) surface-mount format, it supports an operating temperature range from -40 °C to +85 °C.

Battery Management Feature Summary

• Integrated second-level protection circuitry for enhanced safety
• Ultra-low power consumption suitable for portable devices
• Compact WSON-6 package for space-constrained designs

Battery Management Applications

• Portable electronic devices requiring secondary battery protection
• Medical equipment battery packs
• Consumer electronics with Li-Ion or Li-Polymer cells

Battery Management Procurement Notes

Verify the specific suffix DSET corresponds to the tape-and-reel packaging configuration required for your assembly line. Confirm RoHS compliance status through the official datasheet before finalizing procurement. Ensure the ordering quantity aligns with the manufacturer's standard reel sizes to avoid cut-tape handling issues.

Battery Management Selection Notes

Select this component when a dedicated secondary protector is needed alongside a primary control IC. The fixed 4.35 V output threshold suits standard high-voltage lithium cells. Consider the 6-WSON footprint constraints during PCB layout. Verify compatibility with the system's maximum operating voltage of 8 V.

Battery Management Part Context

This part belongs to the Texas Instruments BQ2970 series of advanced single-cell battery protectors. It complements primary battery management ICs by providing independent overvoltage protection. The series is widely used in applications demanding high reliability and low standby current for extended battery life.

Battery Management Replacement Considerations

Check the BQ29700DSET for similar protection functions with different voltage thresholds. The BQ29704DSET offers alternative specifications within the same family. Verify pinout and electrical parameters against the target application requirements before substitution.
