  • DRV8340-Q1: Zener Clamp Diode

    Resolved
    Part Number: DRV8340-Q1 Dear expert, The customer has some question about DRV8340 integrated zener clamp diode. Why external short-circuit events on the MOSFET will cause a overvoltage HS VGS? Why doesn't low side have a z ener clamp diode? If the external…

  • DRV8340-Q1: EN tied to VCC

    Resolved
    Part Number: DRV8340-Q1 Hello Team, I see that all faults can be cleared via the CLR register, is there any reason to not tie EN direcly to VCC? E.g. any function or setting which will require a EN latch? Thanks, Matthias
