General Description
The FM809/810 are supervisor circuits that monitor power supply
or other system voltages and issue reset pulses (FM809 =
RESET, FM810 = RESET) when a fault condition exists. Several
threshold voltages are offered to accommodate system voltages
of 5.0V, 3.3V, 3.0V and 2.7V with different tolerances.
The low supply current (typically 2
μ
A) recommends the devices
for portable designs or wherever power saving is primary.
The minimum RESET delay is 140ms, but this may be changed to
a value between 32-256ms. Contact the factory for more informa-
tion.
