FM1233B Rev. D
General Description
The FM1233B features a highly accurate voltage reference to
which V
CC
is compared. Once V
threshold, it will drive the RESET line and continue to hold it low
until V
CC
returns above the threshold and the time for the
RESET pulse duration has expired. The FM1233B is immune to
short negative going transients on the V
of a 0.1μF bypass capacitor as close as possible to the V
provides additional transient immunity.

systems since common devices are not functional in this range.
If it is desired for the FM1233B reset to be functional below this
range, use a 100K

The FM1233B permits an external pushbutton to initiate a reset.
Such a connection to pin 2 will be debounced, RESET will go
low and recover in typically 250ms. For proper operation, the
external switch should be paralleled by an external capacitor of
100pF to 0.01μF.
