V supply
This circuit monitors the current at the load. As
current flows through the load, a voltage drop with
Load
V D D
respect to ground appears across R sense where
V sense = I load * R sense. The following conditions apply:

Output
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.
