(No phone calls, my wife is having surgery this afternoon :-(
I hope this is just a university project and not a commercial (as in expensive) venture where you will get the blame for a failure ;-)

I love to cook with wine. Sometimes I even put it in the food.
How'd she do?

Thanks,

She's fine! Thanks!
Turned out not to be a brown recluse or such flesh wasting creatures.
Seems a cyst burst inside her finger and a massive infection resulted.
So they opened up her finger and drained and scraped all the "goopus" out of there.
Painful, but she's fine.
Done by a surgeon specializing in hands ;-)

Hi Jim,
Hope your wife's surgery went allright!
Actually it is commercial not university, but i am a newbie at this (and definately not important enough to hire contractors :-) Anyways I think its not appropriate to ask you more questions for free. Will do some research
Thanks qq
Did QQ say there was an actual problem, or he was worried there might be? If it's the latter, my suggestion that he carefully monitor the chip's supply current with and without the FET's parasitic diode conducting, should provide the answer, should it not? If QQ's still in simulation mode, he can check to see if the current is ever high enough through Rds(on) to create diode conduction. If his FET is large enough, this shouldn't happen, and surely that's the end of the "problem."

Yep! Just fine! One of the best hand surgeons in Phoenix did the work.
Feel free to continue to fire away with questions.
I wasn't fishing for a fee... just trying to get down to the root of the problem.

Win, It's a monolithic chip. Not quite the same kind of situation as with a discrete MOSFET...
My concern is latch-up possibilities.
And I've tried, unsuccessfully, to find out why it's a necessary bias condition in the first place.

I understood that, but if the drop from his reverse current is under 500mV...

Thanks,

That's not clear... the application is vaguely defined... purportedly because of proprietary concerns.
"Possible bias" is a not-allowed condition in monolithic design... Murphy ALWAYS wins ;-)
