LM5122-Q1: Over Temperature protect funtion

ZYT
Intellectual 350 points
Part Number: LM5122-Q1

Hi all,

i have some questions about LM5122Q1 over temperature function.

if the junction temperature exceed 165C ,   how does the over temperature orotect funtion work?

if the over temperature  event disappear, can the controller re-start by itself ?

how can i test the over temperature point ?   how about the over temperatue accuracy ?

thanks a lot.

    When over temperature protection is triggered, the circuit will stop switching, and it will restart once the event disappears. Note that the over temperature protection is a mechanism to protect the IC itself. You should not use it as a protection for your external circuit.

    Test it requires a special procedure and you may not read the temperature correctly if you don't have appropriate tools and instruments. Recommend to trust the datasheet info.
