BQ296111DSGR

Battery Management Overview

The BQ296111DSGR is a battery protection integrated circuit designed for lithium-ion battery packs consisting of two to four cells. It provides overvoltage protection and includes an integrated low-dropout regulator (LDO) output. The device operates within a supply voltage range of 3 V to 20 V and features a quiescent current of 4 µA. It supports a maximum output current of 14 mA at 7 V from the LDO. The component is housed in an 8-WSON package with dimensions of 2x2 mm and functions reliably across a temperature range of -40°C to +110°C.

Battery Management Feature Summary

• Provides overvoltage protection for multi-cell lithium-ion battery configurations
• Integrates a low-dropout regulator for auxiliary power supply generation
• Features ultra-low quiescent current consumption for extended battery life
• Supports high operating temperatures suitable for demanding environments

Battery Management Applications

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

Battery Management Procurement Notes

Verify the specific suffix 'DSGR' corresponds to the tape-and-reel packaging format when ordering. Confirm that the 8-WDFN exposed pad thermal requirements are met by the target PCB layout. Ensure the application voltage does not exceed the 20 V absolute maximum rating to prevent device damage during operation or transient events.

Battery Management Selection Notes

Select this component for applications requiring dedicated overvoltage protection combined with a regulated auxiliary voltage source. It is suitable for designs where space constraints favor the compact 8-WSON footprint. Consider the 4 µA standby current for energy-sensitive portable products. Verify compatibility with the specific lithium-ion chemistry voltage thresholds defined in the datasheet.

Battery Management Part Context

This part belongs to the BQ2961xx series of battery management ICs from Texas Instruments. It complements other battery protection solutions by offering integrated regulation capabilities alongside cell monitoring. The series is designed to enhance safety and reliability in portable electronics, providing a compact alternative to discrete protection circuits.

Battery Management Replacement Considerations

The BQ296100DSGT is a documented substitute within the same family, offering similar overvoltage protection and LDO functionality. Verify pin-to-pin compatibility and electrical parameter alignment before substitution. Check for any differences in package marking or thermal characteristics between the DSGT and DSGR variants.
