BQ29330DBTR

Battery Management Overview

The BQ29330DBTR is a battery protection analog front-end (AFE) designed for two, three, and four-cell lithium-ion or lithium-polymer battery packs. It operates within a supply voltage range of 4.5 V to 25 V and supports an output voltage of 25 V with a maximum output current of 50 mA. The device functions reliably across an extended temperature range from -40°C to +110°C. Packaged in a 30-pin TSSOP, it integrates external short-circuit protection capabilities to safeguard the battery system against fault conditions.

Battery Management Feature Summary

• Provides comprehensive protection for multi-cell lithium-based battery architectures
• Integrates external short-circuit detection mechanisms for enhanced safety
• Supports operation with both lithium-ion and lithium-polymer chemistries

Battery Management Applications

• Protection circuits for portable electronic devices
• Battery management systems in power tools
• Uninterruptible power supply (UPS) battery packs
• Medical equipment battery assemblies

Battery Management Procurement Notes

Verify the specific suffix 'DBTR' corresponds to the TSSOP-30 package and reel packaging configuration. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure design compatibility with the required operating voltage and temperature specifications for the target application environment.

Battery Management Selection Notes

Select this component when designing protection schemes for 2S to 4S lithium battery configurations requiring integrated AFE functionality. Consider the thermal performance limits and package constraints during PCB layout. Validate that the external circuitry meets the necessary current handling requirements for the intended load applications.

Battery Management Part Context

This part belongs to the BQ29330 series of battery protection AFEs from Texas Instruments. It is often paired with gas gauge ICs such as the BQ20Z40PW or BQ20Z70PW-V160 to form complete battery management solutions. The device focuses on hardware-level protection rather than digital fuel gauging.

Battery Management Replacement Considerations

The BQ29330DBTRG4 is a verified equivalent variant within the same product family. Both parts share identical functional specifications and pinouts. Verify package orientation and marking differences if substituting between these specific orderable codes.
