Is there anything wrong with my Hbridge / Gate driver circuit?
« on: June 16, 2026, 10:11:25 pm »
Gate Driver = IRS2301STRPBF

NMOS = IRF640NPBF

MCU = ESP32-C6-MINI-1-N4

Diode = ES1D

Switching Speed = 100us on time, 10 to 20ms off time for each side with 1ms deadtime.

The jumpers in the middle of the Hbridge are for experimentation of different loads after PCB is manufactured.

Added Schematic with Sources attached to VS. I dont know how to remove the original picture.
