  • The TS831 is an ultra low power integrated circuit incorporating a high stability band-gap voltage reference and a comparator 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 comparator exhibits a 20µs response (with 10mV overdrive) and has an open drain output active 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 reset operation.

    Key Features

    • INTERNAL BUILT-IN HYSTERESIS
    • FAST RESPONSE TIME : 20µs FOR A 10mV OVERDRIVE
    • ULTRA LOW POWER CONSUMPTION :12µA maximum
    • THRESHOLD VOLTAGE:\t4.33V typ. FOR TS831-54.50V typ. FOR TS831-42.71V typ. FOR TS831-3
    • PRECISION RESET THRESHOLD
    • OPEN DRAIN OUTPUT COMPARATOR
    • PIN TO PIN COMPATIBLE WITH MC33064 AND MC33164
    • GUARANTEED RESET OPERATION FOR VCC DOWN TO 1V
