DRV8334: DRV8334 VGS_LVL functionality

Jonathan Fritsch
Prodigy 130 points
Part Number: DRV8334

Tool/software:

I see in the datasheet in MON_CTRL3 a bit called "VGS_LVL". Is this threshold solely used for the VGS protection, or does it play a role in other aspects of the gate driver (eg, smart gate drive)?

    Hi Jonathan, 

    This bit is solely used for the VGS monitoring to select the threshold at which the driver considers the VGS voltage sufficiently on. This does not impact smart gate drive but is used only for fault reporting. the TDRVN and TDRVP, ect. are what determines how long the various gate currents are applied.
