This circuit monitors the current at the load. As
current flows through the load, a voltage drop with
respect to ground appears across R

A simple voltage monitor can be constructed by connecting several voltage detectors as shown above. Each LED will
sequentially turn on when the respective voltage detector threshold (V
DET
+V
HYS
) is exceeded. Note that detector
thresholds (V
DET
) that range from 0.9 V to 4.9 V in 100 mV steps can be manufactured.
