Yes I did ear mark one... MD1821 but it would add to my simple board requirement... I contacted a couple manufacturers and will share what I find... I'm sure someone makes it.

Worse comes to worst, I could use a paired mosfet array then add a few resistors... but trying to keep part count down due to size requirements. I can use 0603 but refuse to use 0402 until the pick and place is completely automated... most of them are not even marked. I could get 2 channels like this but would like 4 maybe more later on the same size board. The board is about 80mm x 40mm. It has a SOIC8 uC and SOT323 regulator plus 0805 caps and input reverse protection.

Here's what I got using a array. Not sure if it needs a little cap to reduce the inrush for switched power...
