BQ7692003PWR

Battery Management Overview

The BQ7692003PWR is a battery monitor IC from the bq769x0 family, designed for 3 to 5 series lithium-ion and lithium phosphate battery packs. It operates with a supply voltage up to 25 V and includes an integrated 3.3 V LDO regulator. The device supports I2C communication and features programmable overvoltage, undervoltage, and overcurrent protection thresholds. It accommodates multiple cell chemistries including Li-ion, Li-polymer, and LiFePO4.

Battery Management Feature Summary

• Integrated analog front-end with high-precision voltage measurement for individual cell monitoring
• Programmable protection mechanisms for overvoltage, undervoltage, and short-circuit conditions
• Supports passive cell balancing through external FET control signals
• Includes a low-power SHIP mode to minimize standby current consumption

Battery Management Applications

• Portable medical devices requiring precise battery state monitoring
• Light electric vehicles and power tool battery packs
• Uninterruptible power supply (UPS) systems
• Consumer electronics with multi-cell lithium battery configurations

Battery Management Procurement Notes

Verify that the ordering suffix 'PWR' corresponds to the tape-and-reel packaging variant rather than the tube package. Confirm the specific temperature grade and marking code match project requirements. Ensure compatibility with the intended I2C bus speed and address configuration during procurement validation.

Battery Management Selection Notes

Select this component when designing systems with 3 to 5 series cells requiring integrated protection and monitoring. It is suitable for applications needing low quiescent current and programmable fault thresholds. Consider the TSSOP-20 package constraints for thermal management and PCB layout space in compact designs.

Battery Management Part Context

This part belongs to the bq769x0 family of analog front-end devices from Texas Instruments. It shares architectural similarities with the BQ76930 and BQ76940 but is optimized for lower cell counts. The family targets high-power portable systems with robust safety features and flexible configuration options via digital interface.

Battery Management Replacement Considerations

The BQ7692003PW is the tube-packaged equivalent of this reel variant. For higher cell count applications, the BQ76930 or BQ76940 families offer expanded channel support while maintaining similar interface and protection functionalities.
