Input

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 lithium−ion battery charge detector.
