The inverting and noninverting configuration of the comparators forms a window voltage detector circuit using a resistor divider network, as shown in Figure 7-1 and Figure 7-2. The input terminals can monitor any system voltage above 400 mV with the use of a resistor divider network. The INA+ and INB– terminals monitor for undervoltage and overvoltage conditions, respectively.
