LP38851, LP38852 / themal shutdown tempreture

Other Parts Discussed in Thread: LP38851, LP38852

Hi all,

Would you mind if we ask about LP38851 and LP38852?

 

＜Question＞

How much is the MAX and Min value of thermal shutdown temperature?
We understand the datasheet shows(defines) only typical value.
Furthermore, we can also understand that MIN/MAX values can not be guaranteed.
So, if you can guess the tolerance from the viewpoint of design, could you let us know these?

 Kind regards,
Nagai

    Thermal Shutdown is provided as a safety feature only.

    Operating at Thermal Shutdown indicates that both the specified Operating Ratings Junction Temperature specification (125°C) has been violated, and the ABS MAX Junction Temperature specification (150°C) has been violated.

    Operation with a junction temperature (Tj) above 125°C is not recommended as the device behavior is not ensured. The Typical Value is provided for reference purposes only.

    Best guess from the available information is that Tsd may vary by +/-5°C.
