DESCRIPTION
The DS1233 EconoReset monitors two vital conditions
for a microprocessor: power supply and external over-
ride. A precision temperature compensated reference
and comparator circuit are used to monitor the status of
the power supply (V
CC
). When an out–of–tolerance
condition is detected, an internal power fail signal is
generated which forces reset to the active state. When
V
CC
returns to an in–tolerance condition, the reset sig-
nal is kept in the active state for approximately 350 ms to
allow the power supply and processor to stabilize. The
second function of the DS1233 is pushbutton reset con-
trol. The DS1233 debounces a pushbutton closure and
will generate a 350 ms reset pulse upon release.
