Introduction
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.
Features
- ULTRA LOW POWER CONSUMPTION: 12μA maximum
- PRECISION RESET THRESHOLD
- GUARANTEED RESET OPERATION FOR VCC DOWN TO 1V
- OPEN DRAIN OUTPUT COMPARATOR
- FAST RESPONSE TIME: 20µs FOR A 10mV OVERDRIVE
- INTERNAL BUILT-IN HYSTERESIS
- PIN TO PIN COMPATIBLE WITH MC33064 AND MC33164
Applications
- Power-on reset generator for microcontroller
- Power failure detector
