It is not recommended to use the INA250 for inline current measurements with PWM inputs. Please look into the INA240 and especially the INA253 for this kind of application.
A fast-edge pulse, while not damaging to the device, will cause the input ESD cells to turn on very briefly. A very small amount of heat is generated through the ESD cell. Normally this is fine but providing sustained, high frequency pulses from a PWM will cause the part to heat up over time. Filtering the signal at the inputs of the INA will slow the edges down and provide better operating conditions.
