LTC4366 VDD and SD voltage

Hello,

I have been using LTspice to check how the LTC4366 works.

When a surge comes in from the input, the VDD pin voltage exceeds its absolute maximum voltage 10V.

Please refer to the attached document. 

The VDD pin is clamped to 12V internally, so I don't think it's a problem, but I asked it because the voltage exceeds the absolute maximum rating.

Regards,

Kazu
