BQ294604DRVT

Battery Management Overview

The BQ294604DRVT is a battery overvoltage protection device designed for two or three series-connected lithium-ion or lithium-polymer cells. It operates within a supply voltage range of 3 V to 8 V and features an ultra-low operating current of 1 µA. The component supports output voltages from 300 mV to 30 V and functions reliably across a temperature range of -40°C to +85°C. Packaged in a compact WSON-6 surface-mount format, it provides essential protection against cell overvoltage conditions.

Battery Management Feature Summary

• Provides dedicated overvoltage protection for multi-cell lithium-based battery packs
• Features ultra-low quiescent current consumption for extended battery life
• Supports operation with both lithium-ion and lithium-polymer chemistries

Battery Management Applications

• Portable electronic devices requiring multi-cell battery management
• Consumer electronics utilizing series-connected lithium batteries
• Battery-powered tools and equipment with overvoltage safety requirements

Battery Management Procurement Notes

Verify the specific suffix DRVT indicates tape-and-reel packaging when sourcing components. Confirm that the part number corresponds to the Texas Instruments BQ2946xx family specifications. Ensure compatibility with the intended battery cell count and voltage thresholds before integration into the design.

Battery Management Selection Notes

Select this component for applications requiring protection of two or three series cells. Consider the WSON-6 package size for space-constrained designs. Evaluate the low standby current requirement against system power budgets. Verify that the operating temperature range meets the environmental conditions of the target application.

Battery Management Part Context

This device belongs to the BQ2946 series of battery protection ICs from Texas Instruments. The series offers various configurations for single and multi-cell lithium battery protection. The BQ294604 variant specifically targets two or three series cells, distinguishing it from single-cell or higher-count alternatives within the same product line.

Battery Management Replacement Considerations

Check for other BQ2946xx variants with different cell counts or OVP thresholds. Verify pinout and package compatibility if substituting with similar protection ICs from other manufacturers.
