TPIC74100-Q1 waveform in power off

Other Parts Discussed in Thread: TPIC74100-Q1

I fixed waveforn in ramp up (add 1uF capacitor).

But there is the small peak in the power off.

I attacked the file.

I have questions.

1. Why is it occured (in the red circle at CLP pin)? What is the cause?

2. Does TPIC74100-Q1 (CLP pin) have the peak in power off?

3. Are there any solutions for improving the peak?

Best regards,
