Part Number: ISO5851
I am using ISO5851 to drive some Mosfets (IXFN180N25T). They are configured into four half-bridges. The inputs on the chip seem to be getting pulled around. My circuit uses the sample circuit shown in the data sheet with a bi-polar isolated DC supply. Does anyone have experience with this chip? Any advice or pointers will be greatly appreciated.
Could you please the DESAT diode and float the Miller clamp pin and try it again? What are the values of VCC2 and VEE2? I would recommend to try it on one switch first before you hook up all the four half bridges. Let's know how it goes.
In reply to Xiong Li:
I have the Desat connected directly to Out . VCC2 to GND2 is +15VDC and VEE2 to GND2 is -15VDC.
The Miller Clamp is floating.
