1 / 11 page 1/11 s ULTRA LOW POWER CONSUMPTION : 12 µA maximum s PRECISION RESET THRESHOLD s THRESHOLD VOLTAGE: 4.33V typ. FOR TS831-5 4.50V typ. FOR TS831-4 2.71V typ. FOR TS831-3 s GUARANTEED RESET OPERATION FOR VCC DOWN TO 1V s OPEN DRAIN OUTPUT COMPARATOR s FAST RESPONSE TIME : 20 µs FOR A 10mV OVERDRIVE s INTERNAL BUILT-IN HYSTERESIS s PIN TO PIN COMPATIBLE WITH MC33064 AND MC33164 DESCRIPTION The TS831 ultra low power integrated circuit incor- porates a high stability band-gap voltage refer- ence and a comparator with open drain output. The threshold voltage is set at 4.33V for TS831-5, 4.5V for TS831-4 and 2.71V for TS831-3 by inter- nal thermally matched resistances. The comparator exhibits a 20 µs response (with 10mV overdrive) and has an open drain output ac- tive when input voltage is lower than the threshold. An internal hysteresis, 100mV for TS831-4/ TS831-5 and 60mV for TS831-3, increases the comparator’s noise margin and prevents false re- set operation.
