BQ771611DPJR

Battery Management Overview

The BQ771611DPJR is a battery protection integrated circuit designed for lithium-ion and lithium-polymer battery packs. It supports configurations of two to four series-connected cells. The device provides overvoltage protection by disconnecting the charge path when cell voltage exceeds the threshold. It operates within a supply voltage range of 3 V to 25 V and functions across an industrial temperature range of -40°C to +110°C. The component is housed in an 8-WSON package measuring 3 mm by 4 mm with a bare pad.

Battery Management Feature Summary

• Provides overvoltage protection for multi-cell lithium-based battery packs
• Supports 2S, 3S, and 4S battery configurations
• Operates at low quiescent current for extended standby life
• Integrated charge control switch management

Battery Management Applications

• Portable consumer electronics battery packs
• Power tool battery modules
• Medical device power supplies
• Uninterruptible power supply (UPS) systems

Battery Management Procurement Notes

Verify the specific suffix DPJR against the official Texas Instruments datasheet to confirm the reel quantity and tape-and-reel specifications. Ensure that the ordering information matches the required packaging format for automated assembly processes. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and traceability before procurement.

Battery Management Selection Notes

Select this component for applications requiring simple overvoltage protection without active balancing or coulomb counting features. It is suitable for designs where cell monitoring is handled externally or where only basic safety cutoff is needed. Consider the WSON package size constraints and thermal dissipation requirements relative to the PCB layout and ambient operating conditions.

Battery Management Part Context

This part belongs to the BQ7716xx family of battery protection ICs from Texas Instruments. The family includes variants such as BQ771602 and BQ771612, which share similar functional architectures but may differ in specific thresholds or internal switch characteristics. These devices are positioned as cost-effective solutions for fundamental battery safety in portable energy storage applications.

Battery Management Replacement Considerations

Direct substitutes within the same family include BQ771602DPJR and BQ771612DPJR. Verify pin compatibility and electrical parameter alignment with the system design before substitution. Alternative packages or manufacturers require full re-validation of interface timing and protection thresholds.
