Abstract

A circuit for providing programmable hysteresis levels is disclosed. The circuit includes comparators for producing output signals when an input signal crosses respective set points and a hysteresis circuit for establishing a hysteresis in the output signals. When a comparator's output signal is "on", the input signal is shifted by a hysteresis differential. The output signal is terminated when the shifted input signal returns to the set point. The hysteresis circuit includes a programmable hysteresis input for adjusting the hysteresis differential to different preset and intermediate hysteresis levels.
