Part Number: TPS7B7702-Q1
I'm trying to sale of TPS7B7702, now.
And I have a question about this product.
(I'm asked by this customer for this thing.)
So, please teach me about this thing.
Junction temperature (Tj) of absolute maximum rating: - 40 to 150 ° C and ambient temperature (TA): - 40 to 125 ° C.
However, Thermal shutdown detection temperature of this product is 175 ° C @ TYP (Junction).
In such a condition, I think that the detection temperature of Thermal shutdown is 150 ° C @ TYP and it is necessary to have hysteresis of about 15 ° C.
(This is because there is concern that "If the ambient temperature has reached near the rated rating, it is not reset if the IC is detected at 175 ° C.")
Is my consider a mistake?
Could you help us?

Hi Jason Liu-san,
Thank you very much answering.
＞When device working under junction temperature range from 150 °C to TSD, device could still work, but the device lifetime would be shorten very much.
Therefore, I think that it is necessary to apply thermal shutdown so that the junction temperature does not exceed the rating (150℃).
I asked the meaning, but is my considering a mistake?
