I have some questions for TPS60402 and TPS60402-Q1.
Regarding TPS60402, its operating temperature range is defined as Tj (-40 to 125C).
But, its electoral characteristics is specified with Tc = -40 to 85C range.
Because Psi_JT is 3.3C/W, Tj is almost the same as Tc.
What does it mean? Does it just want to say this device should be used within Tc = -40 to 85 range.
Tj = -40 to 125C recommended range desn’t have so much meaning?
My customer is considering to migrate from TPS60402 to TPS60402-Q1.
As far as I checked the both datasheets, the differences between them look like temperature range and ESD range.
Is there any other difference between them?
