Hi Team,

As for some automotive electronic product/application, they have requirement about passing iso 7637 5b

May I ask whether LMR33630-Q1 can meet the requirements of 7637 5b for these kinds of automotive electronic products?]

Thanks!

Hi,

LMR33630-Q1 could support the test if the Vin-GND pin voltage is kept below 38V for the transient. But on actual tests, it's better to use an input transient protection (typical TVS circuit) on the input in case any unexpected spikes on wire. Thanks.
