    Hello,

    I would like to design a closed loop motorcontroller for a medium sized motors (max 10A and 35V):
    https://www.pololu.com/product/3218 (maybe 2 in parralel).
    For the mosfet is would like to use this one PSMN4R0-40YS:

    Now i want to use a matching gate driver for the system.
    I roughly calculated that i need a dead time of 200nS.
    First i wanted to use the MC33883 gate driver but this chip has no deadtime control and shootthrough protection and is more 'difficult' to control.

    I have also found the TLE7181EM (from international rectifier) and this chip have a more use friendly control, sense amplifiers and other features but have lower driving capabilities. Is this one good enough for this application because is seems to used in low cost applications?

    I have also no clue to calcultate Rgate and the snubber network?
