DRV8301

Iam working on drv8301.I got in a problem that when i give the PWM input ,the gate output does not change(MOSFET did not turn ON).

GVDD=11.2V

AVDD=7.5V

DVDD=4.5V

my ground pad is soldered perfectly as SPI is working.I don't know why my AVDD and DVDD are higher then the expected value(6.3V and 3.3V).I have also checked my circuit.....all the connections are good.My circuit is same as given in the datasheet.One more thing i disabled the OC protection by SPI to make the testing easy.

please help me.
