Hello,
I've tested the LM74701-Q1 with 2 power supplies of 54V and 2 N-Mosfet (IAUZ40N06S5N050ATMA1) with Vds:60V, Id: 40A, Rds On: 5mOhm, Vgs: -20V;+20V, Qg: 23.5 nC
I've connected pin EN to the ANODE and left SW pin floating. When i plugged both of my PSU, i think one of the mosfet (or both) fried because now the Drain and Source of the mosfet are shorted.
I think it's because i'm using a voltage above the Vclamp (43V max). But in the datasheet it allowed 3.2-V to 65-V input range into the Anode.
My Objective is to use ORing solution instead of Schottky diode to block reverse current and have low forward voltage.
Can you confirm that my problem comes from my voltage being higher then Vclamp ?
Thank you in advance !
