*Stresses above those listed under Absolute Maximum Ratings may cause perma-
nent damage to the device. This is a stress rating only; functional operation of the
device at these or any other conditions above those listed in the operational sections
of this specification is not implied. Exposure to absolute maximum ratings for
extended periods of time may affect device reliability.

RESET(1)
Power Supply Input; +5 V.
Voltage Monitoring Input.
0 V. Ground reference for all signals.
Logic Output. RESET(1) goes low if V
MON
falls below the Reset Threshold or the Watch-
dog timer is not serviced within its timeout
period. The reset threshold is typically 4.4 V
for the ADM9690. RESET(1) remains low
for 50 ms after V
CC
returns above the thresh-
old. RESET(1) also goes low for 50 ms if the
Watchdog Timer is not serviced within its
timeout period.
Logic Output. RESET(2) goes low simulta-
neously with RESET(1) but remains low for
an additional 10 ms.
Watchdog Input. If an edge is not detected on
WDI within the selectable watchdog timeout
period, RESET(1) and RESET(2) are forced
low for their respective timeout periods. The
watchdog timer restarts with each positive
or negative going transition on the WDI
line. Following a reset it is restarted when
RESET(1) goes inactive (high). The Watch-
dog Timer may be disabled if WDI is left
floating or is driven to midsupply.
Watchdog Timeout selection inputs. Refer to
Table I.
