DRV8432: Vreg=0.48v

Part Number:DRV8432

I am using DRV8432 first time for a motor control application.

Gvdd=vdd=12v,Pvdd=12v.

I am working in 1PFB mode.M0=0,M1=Vreg,M3=0.RESET_CD=0v.Reset_AB=NC.PWM_B and PWM_B=0.

After power is switched on voltage on I get Fault pin=0, OTW=1.65V, Vreg =0.48 .

Connecting RESET_AB to 0v. doesn't make any difference.

Unable to get device working.

Unable to locate the fault.

Please help.
