The above circuit combines an active high and an active low reset output device to form
a window detector for monitoring battery or power supply voltages. When the input
voltage falls outside of the window established by the upper and lower device
thresholds, the LED will turn on indicating a fault. As the input voltage falls within the
window, increasing from 1.0 V and exceeding the active low device’s hysteresis
threshold, or decreasing from the peak towards 1.0 V and falling below the active high
device’s undervoltage threshold, the LED will turn off. The device thresholds shown can
be used for a single cell lithiumion battery charge detector.
