3. Correct, it's auto-retry.

For TI's policy, I will first click resolved button.

Hi Miranda,

4. You can refer to figure16. It's the first time to response to OC.

5. Section 9.3.1 describe the OC protection mechanisms in details.

   In general, as light load OC, won't thermal cycle and will limit it to Ios.

   As with heavy load OC, will first limit to Ios and for a period of time, will thermal cycle.
