Simplified Functional Diagram of the LMD18200 Current Sensing Circuitry - A simplified functional diagram of the current sensing circuitry of the LMD1

Simplified Functional Diagram of the LMD18200 Current Sensing Circuitry - A simplified functional diagram of the current sensing circuitry of the LMD18200 is shown in the following schematic.

According to the datasheet, LMD18200 has a unique feature circuitry that allow the sensing of current through the load without affecting the supply or ground return lines.

A common method for sensing the load current is to insert a small valued power resistor in series with either the VCC supply or ground lines and detect the voltage drop across this resistor.
