BQ296232DSGT

Battery Management Overview

The BQ296232DSGT is a secondary overvoltage protection (OVP) device for 2-series, 3-series, and 4-series lithium-ion battery packs. It features a fixed delay timer that triggers an active-high output upon detecting overvoltage conditions. The device provides a regulated 3.15 V output with a maximum current of 2 mA to power always-on circuits like RTCs. It operates within a supply voltage range of 3 V to 20 V and draws 1 µA during operation. The component is housed in an 8-pin WSON package and functions reliably between -40°C and +110°C.

Battery Management Feature Summary

• Provides individual cell monitoring for overvoltage detection in multi-cell lithium-ion configurations.
• Includes a self-disable feature that cuts the regulated output when battery voltage drops below a threshold to prevent deep discharge.
• Offers a high-precision OVP threshold with a tolerance of ±10 mV.

Battery Management Applications

• Laptop computers
• Ultrabooks
• Medical devices
• Uninterruptible Power Supplies (UPS)
• Backup battery systems

Battery Management Procurement Notes

Verify the specific suffix 'DSGT' against the manufacturer's official datasheet to confirm the exact overvoltage threshold and delay time options. Ensure the ordering information matches the required regulatory compliance standards, such as RoHS status, before finalizing procurement. Cross-reference the package type and pinout with design files to guarantee physical compatibility.

Battery Management Selection Notes

Select this component when precise overvoltage protection is required for 2S to 4S lithium-ion battery architectures. The integrated regulated output simplifies designs needing a stable voltage source for auxiliary components. Consider the low quiescent current and small footprint if space efficiency and battery longevity are critical design constraints.

Battery Management Part Context

This part belongs to the Texas Instruments BQ2962 series of battery protection ICs. The series is engineered specifically for secondary protection roles in portable electronics. Variants within the family differ primarily in their factory-set overvoltage thresholds and internal delay timer durations, allowing customization for various battery chemistries and safety requirements.

Battery Management Replacement Considerations

Compatible substitutes include other BQ2962 variants such as BQ296231DSGT or BQ296233DSGT, provided they match the required overvoltage threshold and delay timing specifications. Verify that any replacement maintains the same 8-WSON package dimensions and electrical characteristics.
