BQ771604DPJT

Battery Management Overview

The BQ771604DPJT is a battery management integrated circuit designed for overvoltage protection of lithium-ion and lithium-polymer cells. Manufactured by Texas Instruments, it operates within an ambient temperature range of -40°C to +85°C. The device features a low operating supply current of 1 µA and is housed in an 8-WSON package with dimensions of 3x4 mm. It supports cell counts from two to four and includes humidity sensitivity classification.

Battery Management Feature Summary

• Provides overvoltage protection for individual lithium-ion and lithium-polymer battery cells
• Operates with ultra-low quiescent current consumption for extended battery life
• Integrated into a compact surface-mount WSON-8 package

Battery Management Applications

• Portable electronic devices requiring multi-cell battery protection
• Power tool battery packs
• Medical equipment with lithium battery systems

Battery Management Procurement Notes

Verify the specific suffix DPJT against official Texas Instruments documentation to confirm the reel quantity and tape specifications. Ensure compatibility with the target PCB footprint for the 8-WSON package. Confirm RoHS compliance status through the manufacturer's latest environmental declaration before finalizing procurement orders.

Battery Management Selection Notes

Select this component when designing circuits requiring dedicated overvoltage protection for up to four series-connected lithium cells. Consider the -40°C to +85°C operating range for industrial or consumer applications. Evaluate the 1 µA standby current requirement against system power budgets to ensure efficient energy management during idle states.

Battery Management Part Context

This part belongs to the BQ7716xx family of battery protection ICs from Texas Instruments. It serves as a specialized solution for monitoring cell voltages and disconnecting the pack upon detecting overvoltage conditions. The device complements other PMIC offerings by focusing specifically on safety-critical cell-level protection rather than general power regulation.

Battery Management Replacement Considerations

The BQ771602DPJR is a documented variant within the same family supporting similar cell configurations. Verify pinout compatibility and functional equivalence with official datasheets before substitution.
