Part Number: DRV8323

We're running a DC motor through DRV8323 by applying a PWM with constant duty cycle with Vdc as 24V. 

I applied a constant duty cycle when no motor was connected to it's terminals and suddenly sparks came out and the chip burned. I've attached a photo of the burned chip. 

Can you please indicate what could be the reason for the chip's burning.
