Looking for something like a MAX40200 in a SOT-23 case
« on: February 22, 2018, 11:19:18 am »
The MAX40200 ideal diode current switch looks almost ideal for a problem I wish to solve, but (there's always a but) what I'm looking for would have two of them configured in a SOT-23 format just like the BAT54C which I'm looking to replace in a dual supply steering application without changing the PCB.

Does anyone know of a product like that?

Thanks
David

So-called ideal diodes usually need a reference potential (GND), so I doubt you can find a dual ideal diode in a 3-pin package.

One option would be to design a small adapter (provided that you can have access to GND nearby and that there is enough available space on your board).
If a 2.5V to 5.5V operating range fits your requirements, the LTC4413 could be a match. You'd still need an adapter.

Thank you,

I just hate those DFN surface mount ICs.  The LTC4411 http://www.linear.com/product/LTC4411 might fit the bill with some extra components.

I wish they made the 4413 in a SOT type package, as I'm sure I could find a ground nearby.

Does anyone else have any suggestion.

Dave
