WINDOW COMPARATOR
The inverting and noninverting configuration of the comparators forms a window-comparator detection circuit
using a resistor divider network, as shown in Figure 17 and Figure 18. The input pins can monitor any system
voltage above 400 mV with the use of a resistor divider network. INA+ and INB– monitor for undervoltage and
overvoltage conditions, respectively.
