UCC21750QDWEVM-025: Only negative voltage in the output

Part Number: UCC21750QDWEVM-025
Other Parts Discussed in Thread: UCC21750


I am using this evaluation board to check how the UCC21750 works.

I have supplied the board with my own circuits and i have disabled the once installed on it. I supply the VCC pin with 5v, the VDD pin with 15V and the VEE pin with -10V.

In the other hand, i enter a PWM signal with 5V of amplitude to the IN+ pin. Everything seems to be correct in the input pins of the UCC21750, but in the OUTH/L outputs i just see the -10V, wich is the voltage i am supplying the VEE pin for the switching off of the driver. 

I wanna see how the driver conmutes in the gate-source output. I would appreciate if you could guide me.
