Part Number: LM9061

Hi all,

I'm using the LM9061 on a system as an OVP.

one of the requirement of a new design I have, is to have a low side protection.

do you have an application note to operate as a low side protector?

Hi Brian,

my problem is that I wish to identify a positive voltage going over 22V, and drive a low side latch.
I think that LM5067 will identify a negative voltage, right?

Th LM5067 is a low side hotswap IC. Normally gnd isn't interrupted, but it can be used to do so.
