Why IHM06A1driver gets voltage drop while getting power on when motor is in rest condition?

Hello

I am using IHM06A1 driver with STM32F401RE to control stepper motor. I am supplying 5v and 0.300A for motor (according to motor datasheet ) using DC Power Supply and providing 3V/5V to IMH06A1 from STM32F401RE board. There is voltage drop at time of giving power from 5V and 0.300A to 2.5v and 0.300A as I noticed from DC Power Supply when motor is in rest condition but when motor getting power (start rotating) then time everything is ok, there is no drop of voltage. If voltage is there then it may burn device because it goes maximum current. I remove all wire connected again but no improvement.

Please help me to solve this problem and also tell me why I am getting this problem.

Thank You
