Hi all.

I will use an AT89C51 inside a car to drive 2 DC motors with an optocouple H- bridge.
In the lab it works fine. Now I am installing it inside the car and I use a DC/DC converter ( 10 KHZ ) to maintain the CPU isolated from the battery car.
The question is if for the power supervisor, remember is a “clean” supply (I supposed ?) I must use some special supervisor. I have seen in Maxim´s web page that they recommend some supervisors for use in car.
Does anyone have experience ?

Thanks.
Daniel
