Circuit Timing (Ex: FM1233D)
When operating properly with 5V V
also be about 5V. When V

ground ("issues a RESET") and stays there unless V
falls below its minimum operating voltage, approx. 1V. At this
point, the supervisor loses control, and its output may rise, only
to again follow V
CC
down to the ground.

When V
reached, whereupon the device regains control, RESET is
pulled to ground, etc. When V
comes out of RESET 140 ms later.

If it is required that a lower value than GND + 1.0V is needed
on RESET signal during V

≤
1V, a 100K resistor may be used
on the device output to GND.
