Pre-cision Monolithics comparator CMP-02 tums on heating-element driver Q1 when temperature drops below set point determined by ratio of R1 to R2, as sensed by +5 V voltage reference REF02 serving as thermometer. Circuit also provides adjustable hysteresis, determined by R6 and R7, if this feature is desired. Values in parentheses are for 60℃ set point. REF-02 should be thermally connected to substance being heated. Design equations are given.- Linear & Conversion I.C. Products, Precision Monolithics, Santa Clara, CA, 1977-1978, p 15-4.
