UHU-Servo Mosfet drive problem

[Danii]

Hello all,

We have recently made PCB's for UHU-Servo and i am into testing of our first servo motor. The problem is that I am unable to find Mosfer Driver IC IR2184, Instead I have IR2104. I know they are not pin competeble. But please tell me if i can use IR2104 in place of IR2184. If yes then Also tell me appropiate pin change. If not how can i test that my mosfet are working or not.

Thanks
Dani.

Danii,

They are not pinout compatible. Here are the pinouts.

Pin - 2104 - 2184
1 --- VCC -- IN
2 --- IN ---- ~SD
3 --- ~SD -- COM
4 --- COM -- LO
5 --- LO ---- VCC
6 --- VS ---- VS
7 --- HO ---- HO
8 --- VB ---- VB
