Hi,

I need to do an overvoltage protection circuit for high current (30A)
needings.
It's for a vehicle powered circuit. Car or Truck (12 or 24v).

The "Load Dump" fenomenum makes car voltage up to 80v or higher.
The use of transorbs or proctection diodes require a series resistor that
dissipates a lot of power and/or generates undesireable drop voltage.

I didn=B4t find good single chip solutions for this high current scenario.

I've project a FET based circuit (attached) but I don't know if it will be
the best choice.

 Do anybody have some suggestion ?

Thank you.

Luis.
