thermal shutdown threshold for LT8631

Category: Hardware
Product Number: LT8631

The data sheet says part has thermal shutdown, but does not specify the threshold. Can you confirm it does have thermal shutdown and what is the threshold?

  • Hello,

    datasheet states this:

    Honestly there is no need to spec a detailed OT threshold, because you should not design the part with this threshold in mind. It's there to prevent catastrophic failure, but it's not there to be a 'valid' state of operation. Aim for a design that will be safe to operate in all intended conditions depending on ambient temperature, maximum Vin and Iout. 

    The H-grade is specced for 150C junction temperature so the OT trip point will be at higher temperatures.
