MICROPOWER VOLTAGE SUPERVISOR RESET ACTIVE LOW s ULTRA LOW POWER CONSUMPTION : 12µA 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 PARATOR s FAST RESPONSE TIME : 20µs FOR A 10m V OVERDRIVE s INTERNAL BUILT-IN HYSTERESIS s PIN TO PIN PATIBLE WITH MC33064 AND MC33164 DESCRIPTION The TS831 is an ultra low power integrated circuit incorporating a high stability band-gap voltage reference and a parator with an 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 internal thermally matched resistors. The parator exhibits a 20µs response (with 10m V overdrive) and has an open drain output active when input voltage is lower than the threshold. An internal hysteresis, 100m V for TS831-4 / TS831-5 and 60m V for TS831-3, increases the parator’s noise margin and prevents false reset operation.
