Device with ISO5500 driver modification

user4079870

Hi,

I made a MOSFET driver with ISO5500 and I used two voltage sources: -15V and +15V. Now I want to modification my device and use only +15V.

I attach schema. On the blue colour is the first schema, and modification is on the red. Can I short point 18 and 19 and drop out - 15V source only? Have I drop out C6 and C3? Will it work?

Thank You very much for help.

Hi,

Yes, you have the right circuit. I suggest you keep C6 still and can remove C3, if your connection between VE and VEE-P is strong in layout. On the other hand, keeping C3 will not cause any problems. C4 is serving no purpose, and can be deleted.

Rgds,
