BQ296212DSGR

Battery Management Overview

The BQ296212DSGR is a battery protection integrated circuit from Texas Instruments designed for lithium-ion battery packs. It provides overvoltage protection specifically for 2-series and 3-series cell configurations. The device operates within a supply voltage range of up to 20 V and delivers an output voltage of 3.3 V with a maximum output current of 1 mA. It functions reliably across an extended temperature range from -40°C to +110°C. The component is housed in an 8-WSON package, measuring 2x2 mm, suitable for surface-mount assembly.

Battery Management Feature Summary

• Provides dedicated overvoltage protection for 2-series and 3-series lithium-ion battery configurations
• Integrates low quiescent current operation to minimize power consumption during standby
• Features a compact 8-WSON package optimized for space-constrained portable electronics

Battery Management Applications

• Protection circuits for 2-cell and 3-cell lithium-ion battery packs
• Portable electronic devices requiring compact battery management solutions
• Consumer electronics utilizing series-connected lithium-ion cells

Battery Management Procurement Notes

Verify the specific suffix 'GR' against official Texas Instruments documentation to confirm tape-and-reel packaging specifications. Ensure compatibility with the target PCB footprint for the 8-WSON package. Cross-reference the exact part number with the manufacturer's latest datasheet to validate active status and environmental compliance details before finalizing procurement orders.

Battery Management Selection Notes

Select this component when designing protection for 2-series or 3-series lithium-ion batteries requiring overvoltage monitoring. The fixed 3.3 V output and 1 mA current capability suit standard logic interface requirements. Consider the 8-WSON form factor for applications demanding minimal board space. Verify that the operating voltage range aligns with the maximum pack voltage of the intended battery configuration.

Battery Management Part Context

This part belongs to the BQ2962 family of battery protection ICs from Texas Instruments. The family includes variants supporting different series counts, such as the BQ296213 for 2- to 4-series cells. These components are classified under Power Management ICs (PMIC) and serve as critical safety elements in lithium-ion battery systems by preventing damage from excessive charging voltages.

Battery Management Replacement Considerations

The BQ296212DSGT serves as a verified alternative offering identical electrical functionality but in a cut-tape package format instead of tape-and-reel. Other family members like the BQ296213 support additional series configurations.
