Manual Reset
This input triggers a reset pulse when pulled below 0.8V. This active
LOW input has an internal 70µA pull-up current. It can be driven
from a TTL or CMOS logic line or shorted to ground with a switch.
Voltage Input
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
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.
No Connect
Active-LOW RESET Output
This output pulses LOW for 200ms when triggered and stays LOW
whenever V
after V
HIGH. A watchdog timeout will not trigger RESET unless WDO is
connected to MR.
Watchdog Output
This output pulls LOW when the internal watchdog timer finishes its
1.6s count and does not go HIGH again until the watchdog is cleared.
WDO also goes LOW during low-line conditions. Whenever V
below the reset threshold, WDO stays LOW. However, unlike RESET,
WDO does not have a minimum pulse width. As soon as V
the reset threshold, WDO goes HIGH with no delay.
Active-HIGH RESET Output
This output is the complement of RESET. Whenever RESET is HIGH,
RESET is LOW and vice-versa. Note that the SP708R/S/T has a reset
output only.
