DRV8841: Shorting of the pins when in use

Part Number:DRV8841

Hello,

I was testing the ic with Vm=24 volts by applying the load of 10.8 ohms and a load coil of 1.2ohms resisrance and 4.2 mH indutance with pwm applied at 50% duty cycle. While testing

I got only error ripples on dso. After checking the circuit  it was found that pins in the power path were short circuited. Kindly suggest me some reason or solution.

(Note : Only one H-bridge was in usage and there are no other short circuits on the circuit board (PCB).
