UCC5350: UCC5350 output not pulling close to VCC2

Part Number: UCC5350

Hello,

I need some help here and this is not the first time I am asking about this device. As shown in the diagram, I am supplying the VCC1 and IN+ with 5V and the VCC2 with 20V. VEE2 with -5V. Ignore the -3V.

When I probe the output, I am expecting the output to pull close to VCC2, but why am I getting 3.2V at VCC2 pin.5 and the output? I have looked at my circuit; there is no missing track or wrong connection, but I still do not understand why I am 3.2V.

Please advise on what to do here.

Regards,
