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

Attached are the data files for the 2 chips and an application note.
Read ALL make notes, and you will teach yourself how to keep the smoke IN.

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
