BQ294532DRVT

Battery Management Overview

The BQ294532DRVT is a battery protection integrated circuit designed for 2- to 3-cell lithium-ion and lithium-polymer battery packs. It provides overvoltage protection with a fixed threshold of 4.5 V. The device operates within a supply voltage range of 3 V to 25 V and features a low operating supply current of 1 µA. Packaged in a compact 6-WSON (2x2) format, it supports surface-mount installation and functions reliably across an extended temperature range from -40°C to +85°C.

Battery Management Feature Summary

• Provides hardware-based overvoltage protection for multi-cell lithium-ion and lithium-polymer battery configurations
• Maintains ultra-low quiescent current consumption to minimize standby power drain in portable applications
• Integrates into small-footprint designs using a six-terminal WSON package suitable for space-constrained electronics

Battery Management Applications

• Protection circuits for 2S or 3S lithium-ion battery packs in consumer electronics
• Battery management systems in portable medical devices requiring high reliability
• Power backup units for industrial equipment utilizing multi-cell lithium configurations

Battery Management Procurement Notes

Verify the specific suffix DRVT indicates tape-and-reel packaging when sourcing components. Confirm that the 4.5 V overvoltage threshold aligns with the target battery chemistry requirements. Ensure the 6-WSON footprint matches the PCB layout constraints. Check RoHS compliance status against regional regulatory standards before finalizing procurement orders.

Battery Management Selection Notes

Select this component when a fixed overvoltage threshold is sufficient without the need for adjustable settings. Consider the 6-WSON package dimensions if board real estate is limited. Evaluate the -40°C to +85°C operating range against environmental conditions. Compare the 1 µA supply current against system power budget requirements for long-term standby operation.

Battery Management Part Context

This part belongs to the BQ2945xx series of battery protection ICs from Texas Instruments. The series includes variants such as BQ294522 and BQ294533, which share similar architectural features but differ in specific overvoltage thresholds and operational parameters. The DRVT designation specifically denotes the reel packaging format used for automated assembly processes.

Battery Management Replacement Considerations

Direct substitutes include BQ294522DRVR and BQ294533DRVT. Verify that alternative parts match the required overvoltage threshold and package type. Ensure compatibility with existing PCB footprints and thermal management strategies when swapping between these family members.
