Part Number: TPS37A-Q1
Why an automotive rated part should comply to the 60664 creepage specification? Nominal working voltage should be 42V in the worst case, so as a SELV, it shouldn't be influenced by clearance/creepage (which usually come in play after 50V). Is this some automotive standard or it's because the inputs are rated 65V? The typical application circuits in page 1 also shows suppression diodes, these should be clamp the voltage to a safe level. Is it that 42V systems have a nominal variation that could go over 50V? Thanks in advance
