This input triggers a reset pulse when pulled below 0.8V. This
active LOW input has an internal 250μA pull-up current. It
can be driven from a TTL or CMOS logic line or shorted to
ground with a switch.
+5V power supply
Ground reference for all signals
Power-Fail Input
When this voltage monitor input is less than 1.25V, PFO goes
LOW. Connect PFI to ground or V CC when not in use.
Power-Fail Output
This output is LOW until PFI is less then 1.25V
Watchdog Input
If this input remains HIGH or LOW for 1.6s, the internal

watchdog timer times out and WDO goes LOW. Floating WDI
or connecting WDI to a high-impedance tri-state buffer
disables the watchdog feature. The internal watchdog timer
clears whenever RESET is asserted, WDI is tri-stated, or
whenever WDI sees a rising or falling edge.

LOW whenever V CC is below the reset threshold (4.65V for the
SP705/707/813L and 4.40V for the SP706/708). It remains
LOW for 200ms after V cc rises above the reset threshold or
MR goes from LOW to HIGH. A watchdog timeout will not
trigger RESET unless WDO is connected to MR .
