BQ771600DPJR

Battery Management Overview

The BQ771600DPJR is a battery protection integrated circuit designed for lithium-ion systems with 2, 3, or 4 series-connected cells. It provides fixed overvoltage protection thresholds and utilizes an external capacitor to program the delay timer. The device operates within a supply voltage range of 3 V to 25 V and supports surface mount installation in an 8-WSON (3x4) package. It functions reliably across a temperature range of -40°C to 110°C.

Battery Management Feature Summary

• Provides dedicated overvoltage protection for 2-, 3-, and 4-series lithium-ion cell configurations
• Features an external capacitor-programmed delay timer for customizable response timing
• Utilizes fixed overvoltage threshold settings for simplified design implementation

Battery Management Applications

• Lithium-ion battery pack protection circuits
• Portable electronic device power management
• Consumer electronics battery safety modules

Battery Management Procurement Notes

Verify component authenticity by checking manufacturer markings against official datasheet specifications. Confirm package type matches the required 8-WSON footprint. Ensure environmental compliance documentation aligns with project requirements. Validate that the fixed threshold configuration meets specific system voltage constraints before procurement.

Battery Management Selection Notes

Select this component when fixed overvoltage thresholds are sufficient for the application. The external capacitor allows flexibility in setting delay times without changing the IC. Suitable for designs requiring compact surface-mount solutions. Verify that the operating voltage range covers the maximum pack voltage during charging cycles.

Battery Management Part Context

This part belongs to the Texas Instruments BQ7716xx family of battery protection devices. It shares functional similarities with other variants in the series but differs in specific threshold configurations and programming options. The DPJR suffix indicates the tape-and-reel packaging format suitable for automated assembly processes.

Battery Management Replacement Considerations

Direct substitutes include other BQ7716xx variants such as BQ771601DPJR or BQ771612DPJR, provided their specific threshold values and feature sets match the original design requirements. Cross-reference datasheets to ensure compatibility with existing PCB layouts and control logic.
