    So im making this H-bridge for a car.

    per channel:
    • 36v
    • 50A
    • 500-600Hz PWM

    So i need to drive it with a high-side driver, and i choose the IRS2110

    they have this schematic in the datasheet:

    however, i dont know how to calculate the appropriate diodes capacitors or resistors.

    im thinking a 10-100Ω resistor wouldn't be a bad idea on the gate.

    Would this work?

    the diodes are there to bring the voltage down to not blow the LM7815 (i know its a dirty solution)

    the caps between Vs And Vb are .47µF

    the supply is 37,8v when the batteries are fully charged

    this is what the terminals connect too:
    • x1-1 = Right side of the load
    • x1-2 = left side of the load
    • x1-3 = battery ground
    • x1-4 = 30-37,8v from battery
    • x2-1 = logic 5v
    • X2-2 = logic ground
    • X2-3 = High side left signal
    • x2-4 = High side righ signal
    • x2-5 = Low side left signal
    • x2-6 = Low side right signal
