Hi to all!
I need some help to design a circuit that use a power switch.
In particular I want to implement this schema:
So I need an "high side power switch" that i can control using a microcontroller pin at 3.3V, or with an optocoupler if in the case the 3.3V of the microcontroller pin aren't suffcient.
This power switch should be switching a voltage of about 8.4V and a current of about 32A.
The important thing is that this circuit is not for fast switching, i need a power switch only to turn on and turn off the power for the load.
Can you help me to select some ready solutions (like to the load switch) or some component like the mosfet and the gate drive circuit?
I have looked at your load switch, but they are small for my purpose.
Even some reference design or some other solutions are welcome.
