which is essentially an op-amp controlling the gate of a MOSFET in proportion to the voltage across a current sense resistor. The final circuit adds bells and whistles, primarily in the form of ...

In this state, the output voltage is equal to the input voltage. A current sense resistor is then installed in the output path. When a load is connected, this causes a voltage drop across the ...

The process can be simplified with special circuit arrangements called current-shunt monitors, which are offered as standard ICs. These devices sense the voltage across a shunt resistor and ...
