BQ296232DSGR

Battery Management Overview

The BQ296232DSGR is a secondary overvoltage protection (OVP) device for 2-, 3-, and 4-series lithium-ion battery packs. It features a fixed delay timer triggering an active-high FET driver output with a 5.5-second delay option. The device provides a regulated 3.15 V output capable of sourcing up to 2 mA, suitable for powering always-on circuits like real-time clocks. It operates within a supply voltage range of 3 V to 20 V and includes self-disable functionality to prevent battery depletion when voltage drops below a threshold.

Battery Management Feature Summary

• Provides individual cell overvoltage monitoring for 2- to 4-series lithium-ion configurations
• Includes a factory-set OVP threshold with high precision accuracy
• Features a fixed delay timer to trigger the FET driver output upon overvoltage detection
• Offers a regulated low-current output to power always-on auxiliary circuits

Battery Management Applications

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

Battery Management Procurement Notes

Verify the suffix 'GR' indicates tape-and-reel packaging, distinct from the 'GT' cut-tape variant. Confirm the specific delay time option matches system requirements, as the '32' designation corresponds to a 5.5-second delay. Ensure compatibility with the target lithium-ion chemistry and series count before integration.

Battery Management Selection Notes

Select this component for applications requiring precise secondary overvoltage protection with integrated power regulation. The choice depends on the required delay timing; verify that the 5.5-second delay aligns with safety standards. Consider the 8-pin WSON package size for space-constrained designs and ensure the 3.15 V output meets the load requirements of connected peripherals.

Battery Management Part Context

This part belongs to the Texas Instruments BQ2962 family of battery protection ICs. These devices are designed as secondary protectors to complement primary protection circuits in portable electronics. The family offers various delay options and output voltages to accommodate different battery configurations and application-specific safety timelines.

Battery Management Replacement Considerations

BQ296232DSGT serves as the same functional device in cut-tape packaging. Other variants within the BQ2962 series may be considered if different delay times or output voltages are required, provided the pinout and package dimensions remain compatible.
