I am using STM32 based control board to control a pmsm. I am using a UCC27712 gate driver IC. Observing PWM pulses on scope, they seem to overlap and as duty ratio increases over lap increases. Is the "UCC27712 gate driver IC" is compatible with STM32??

Welcome, @TShar.3​, to the community!

The question of compatibility is a bit confusing, as that can cover several aspects, such as level compatibility, but that doesn't seem to be a problem here.

As for the timing, the UCC27712 has an output interlock and 150-ns deadtime, so output overlap should not occur.
