BQ294704DSGT

Battery Management Overview

The BQ294704DSGT is a lithium-ion protection integrated circuit from the Texas Instruments BQ2947 series, designed for single-cell battery management. It operates within a supply voltage range of up to 20 V and supports Lithium-ion and Lithium Polymer chemistries. The device features a low operating supply current of 1 uA and functions reliably across an extended temperature range from -40 °C to +85 °C. Packaged in an 8-pin WSON format with SMD/SMT mounting, it provides essential protection mechanisms for portable electronic applications requiring compact power solutions.

Battery Management Feature Summary

• Provides accurate cell-by-cell voltage monitoring for lithium-based batteries
• Integrates secondary overvoltage protection capabilities
• Supports surface-mount installation in compact WSON-8 packages

Battery Management Applications

• Single-cell lithium-ion battery protection circuits
• Lithium Polymer battery management systems
• Portable consumer electronics power protection

Battery Management Procurement Notes

Verify the specific suffix 'DSGT' against official datasheets to confirm tape-and-reel packaging specifications. Ensure compatibility with the required operating temperature range of -40 °C to +85 °C for your application environment. Cross-reference the WSON-8 footprint dimensions during PCB layout to prevent assembly errors. Confirm RoHS compliance status through manufacturer documentation before final procurement decisions.

Battery Management Selection Notes

Select this component when designing single-cell lithium battery protection requiring low quiescent current. The WSON-8 package suits space-constrained designs compared to larger SOIC options. Consider the -40 °C to +85 °C operational limit for environmental suitability. Verify that the 20 V maximum supply voltage aligns with system requirements. Compare against other BQ2947 variants if different temperature ratings or pin configurations are needed.

Battery Management Part Context

This part belongs to the BQ2947 family of battery protection ICs from Texas Instruments. The family includes variants like BQ294700 and BQ294712, sharing similar protection architectures but differing in specific electrical characteristics and temperature ranges. The BQ294704DSGT specifically targets single-cell applications with standard industrial temperature limits.

Battery Management Replacement Considerations

BQ294704DSGR is a verified alternative offering identical functionality in a reel-packaged variant. Other BQ2947 series members may serve as substitutes if temperature ranges or specific protection thresholds differ from project requirements.
