Abstract: A circuit (10) and method for providing programmable hysteresis levels is disclosed. The circuit includes comparators (C1-C4) for producing output signals (V01-V04) when an input signal (V(PTAT) crosses respective set points and a hysteresis circuit (38) 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 (40) for adjusting the hysteresis differential to different preset and intermediate hysteresis levels.
