I need to replace a relay contact by a mosfet. The voltage range is 25V to 65V and the output curent is max. 3A. I should protect the mosfet against an short circuit on the load.

I'm searching a part like LT1641, Positve High Voltage Hot Swap Controller, but in 8 pin Dip.

A Smart Highside Power Switch, like BTS442, with an operating voltage of 65V.

Thanks
