Ideal Diode like LT4412

[maltejahn]

Hi,

Im looking for a ideal diode circuit. I found a IC from linear, LT4412.
This IC has a maximum voltage of 28V, but I need a circuit for
42V(max2A). Does anyone know a suitable IC or have an referance design.

Regards
Malte

The LTC4412HV has a maximum input voltage of 40V (36V rated), which can
be further extended by the technique described in AN107. Wouldn't that fit?

Hi,

I search now a suitable Mosfet for my application. I found the
FDB5800(Logic Level, RDSon 6mOhm, 80A(my Idmin 15A) from Fairchild(no
samples available), but I cant get this part (in Germany: Farnell,
Rutronik, Digikey). Does anyone know a good one? A low power
consumption is very important for me.

Thanks
Malte
