TS831-3IPT
数据手册.pdf微功耗电压监控器复位低有效 MICROPOWER VOLTAGE SUPERVISOR RESET ACTIVE LOW
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.
