Part Number: LM76202-Q1

Hi TI support team

We have designed with LM76202-Q1 for automotive protection.

but so far, we have tested in Lab and got failure with ISO16750 Test A (without centralized load dump suppression), and follow TI's document, seem this part only test with Test B of ISO16750.

So, could you please help to advise us some additional passive component for pass Test A ISO16750 with LM76202-Q1

Hi Paul,

LM76202-Q1 does not support unsuppressed load dump events. What is your application use case and end product. ?

Hi,

our application is reader on Bus, power from battery of Bus

That why we need to pass ISO16750-2.

Any suggestion to add on the circuit improvement this point.

How about if we change TVS grade?

Thanks
