UCC21330-Q1: Maximum gate drive source/sink current

Part Number: UCC21330-Q1

Tool/software:

Is the maximum sink/source current specification for the output driver stage (6A/-4A) an internally limited current value? Or is it a warning to the designer to ensure that these current values are not exceeded?

  • Hi Daniel,

    These are internal limitations of the device due to the output stage component resistances that affect the rise/fall time of the load capacitance.

    Please refer to the safety limiting values as warning limits:

    More on this in 5.7 Safety Limiting Values of the product's datasheet.

    Regards,
