My design Challenge:
Design a current sensing circuit to detect a load current of 0-40 Amps, operating at 12 Volts DC. I intend to bring the 0-40 Amps wire on to the PCB using a heavy PCB trace OR running an appropriately thick wire along the surface of the PCB.
The sensing circuit must be high side...that is ABOVE the load, not below it in the ground path. I have evaluated various ‘sense resistor ...
