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
