MR
Manual reset input. The active LOW input triggers
a reset pulse. It is pulled HIGH by a 20k
pull-up
resistor. It is compatible with TTL/CMOS signals
when V
CC
= 5V. It can be shorted to ground
through a mechanical switch. Leave folating or
connect to V
CC
if the function is not used.

PFI
Power-fail input voltage monitor. With PFI less
than 1.25V, PFO goes LOW. Connect PFI to
Ground when not in use.

PFO
Power-fail output. The output is active LOW and
sinks current when PFI is less than 1.25V. If not
used, leave the pin unconnected.

WDI
Watchdog input. WDI controls the internal watch-
dog timer. A HIGH or LOW signal for 1.6sec at
WDI allows the internal timer to run-out, setting
WDO low. A rising or falling edge must occur at
WDI within 1.6 seconds or WDO goes LOW. The
watchdog function is disabled by floating WDI. The
internal watchdog timer clears when: RESET is
asserted; WDI is three-stated ; or WDI sees a ris-
ing or falling edge.

RESET
Active LOW reset output. Pulses LOW for 200ms
when triggered, and stays LOW whenever V
CC
is
below the reset threshold. RESET remains LOW
for 200ms after V
CC
rises above the reset thresh-
old or MR goes from HIGH to LOW. A watchdog
timeout will not trigger RESET unless WDO is con-
nected to MR.
