Hello,

Please teach one more about thermal shutdown.

Q:
Is it an automatic retry or a non-automatic retry?

That is my customer's question.
I would appreciate it if you can teach if you know.

Thank you.

Hi Mayumi,

My understanding is that thermal shutdown has automotic recovery once the IC junction temperature decreases. I notified the product expert to clarify this.

Regards,
Tim
