Hi!
I have bought IR2101 mosfet driver to drive my IRFB3034 N-CH mosfets for my brushless dc motor controller.
When i soldered everything to my new PCB for that application, motor rotates, but doesnt have that momentum that it had with my old version of PCB board.
The reason for that is, in my opinion because high side of mosfet driver output doesnt work correctly.
When LOW INPUT is HIGH, LOW OUTPUT is also HIGH, as it should be.
When HIGH input is HIGH, HIGH OUTPUT is HIGH when it should be only when motor is rotating, and when you force to stop a motor with hand, it stays that way because even with high input on high side driver, output stays low, and there is no current to the motor to start rotating again.
I have to say that on schematics on bouth PCBs (old one that is working, and new one that is not) is THE SAME and i cant figure out what is wrong with it.
Could it be the IR2101 or mosfet problem? Or something else. Maybe faulty Ir2101 on this new board?
Please help me if you know
