Circuit Timing (Ex: FM809)
When operating properly with 5V in (for example), V
OUT
will also
be about 5V. When V
IN
starts to fall, V
OUT
will follow it down as
shown. When V
drops below V
, V
OUT
drops to ground ("issues
a RESET") and stays there unless V
IN
operating voltage, approx. 1V. At this point, the supervisor loses
control, and its output may rise, only to again follow V
IN
down to the
ground.
When V
IN
begins to rise, V
OUT
follows it until 1.0V or so is reached,
whereupon the device regains control, V
OUT
is pulled to ground,
etc. When V
IN
rises above V
TH
, V
OUT
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
CC
≤
1V, a 100K resistor may be used on
the device output (to GND for the FM809, to V
CC
for the FM810).
