ADUM4135 Sat function

Hi Sir

I use the Adum4135 for IGBT in inverter application & found the P10 is too sensitive for IGBT Protect

how to adjust the R&C value as the red circle

Can I shut down the Pin 10 function which keep the IC work correct ?

thanks

    Hallo Nignogs,

    I am not sure if you had a reply via Email etc before. If not, sorry for delay.

    DESAT Threshold is fixed inside the gate driver.
    The external components and/or factors (e.g. temperature of diode, MOSFET/IGBT) can affect the voltages in your system, and changing node voltage on Pin10. Thus the threshold voltage is reached differently.
