BQ296103DSGR

Battery Management Overview

The BQ296103DSGR is a battery protection integrated circuit designed for lithium-ion battery packs consisting of two to four series-connected cells. It provides overvoltage protection by disconnecting the pack when cell voltages exceed safe limits. The device features an integrated low-dropout regulator (LDO) that supplies power to external monitoring or communication circuits, ensuring system stability during fault conditions. It operates within a wide supply voltage range and supports surface-mount installation in a compact WSON-8 package.

Battery Management Feature Summary

• Provides automatic overvoltage protection for multi-cell lithium-ion battery configurations
• Integrates a low-dropout regulator to maintain power for auxiliary system components
• Supports surface-mount assembly in a small footprint package

Battery Management Applications

• Portable electronic devices requiring multi-cell battery protection
• Power tool battery packs
• Uninterruptible power supply systems

Battery Management Procurement Notes

Verify the specific suffix 'GR' against the manufacturer's official datasheet to confirm tape-and-reel packaging and temperature grade specifications. Ensure compatibility with existing PCB footprints and validate that the component meets all required environmental standards for the intended deployment environment before finalizing procurement.

Battery Management Selection Notes

Select this component for applications requiring dedicated overvoltage protection for two to four series lithium-ion cells. Consider the integrated LDO capability if downstream circuitry requires a stable voltage source independent of the main battery rail during fault events. Evaluate thermal performance requirements relative to the operating temperature range specified in the technical documentation.

Battery Management Part Context

This part belongs to the BQ2961xx family of battery protection ICs from Texas Instruments. These devices are engineered specifically for safeguarding rechargeable lithium-ion battery packs against overvoltage conditions. The family offers various pin-compatible options tailored for different cell counts and regulatory requirements.

Battery Management Replacement Considerations

Consult the official BQ2961xx datasheet for verified cross-reference information. Confirm that any substitute part matches the electrical characteristics, pin configuration, and functional behavior documented for the original component.
