If:

ILoad t VDET − /Rsense

ILoad w (VDET −+VHYS)/Rsense

Then:

Reset Output = 0 V

Reset Output = VDD

This circuit monitors the current at the load. As

current flows through the load, a voltage drop with

respect to ground appears across Rsense where

Vsense = Iload * Rsense. The following conditions apply:

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 (VDET− +VHYS) is exceeded. Note that detector

thresholds (VDET−) that range from 0.9 V to 4.9 V in 100 mV steps can be manufactured.
