Product details

Battery Protection IC for 2-4 Cell Li-Ion Packs

The Texas Instruments BQ294700DSGT is a dedicated battery protection IC designed for 2 to 4 series-connected Lithium-Ion cells. Its primary function is over-voltage fault protection, a critical safety feature that prevents cell damage during charging by monitoring each cell's voltage and disconnecting the pack if any cell exceeds a safe threshold. This device is typically deployed in battery management systems (BMS) for power tools, portable electronics, e-bikes, and backup power units where reliable cell-level protection is required.

Package and Mounting for Space-Constrained Designs

Housed in an 8-WSON (2x2 mm) package, the BQ294700DSGT is a surface-mount device suited for compact PCB layouts. The exposed pad provides a low thermal resistance path to the board.

Temperature Grade and Operating Environment

Rated for an operating temperature range of -40°C to 110°C (TA), this IC covers industrial and extended-commercial environments. It can be used in outdoor telecom gear, automotive cabin modules, and industrial battery packs that experience wide thermal swings without performance degradation.

Frequently asked questions

What are equivalent or alternative parts to BQ294700DSGT?

A functional alternative within the same family is the BQ79612PAPRQ1, which is an automotive-grade (AEC-Q100) battery monitor with SPI/UART interface and over-temperature protection, but it supports only 1 cell and targets functional safety applications. For a 2-4 cell monitor with SMBus interface, the BQ2084DBT-V143 is an alternative, though it has a narrower temperature range of -20°C to 85°C and comes in a tube package. Neither is a direct pin-compatible replacement; verify your system requirements before substituting.
