A manual reset input provides debounce circuitry for
minimum reset component count.
The Watchdog Timer provides an independent protec-
tion mechanism for microcontrollers. When the micro-
controller fails to restart a timer within a selectable
time out interval, the device activates the WDO signal.
The user selects the interval from three preset values.
Once selected, the interval does not change, even
after cycling the power.

Function
V2 Voltage Fail Output.
This open drain output goes LOW when V2MON is less than V
TRIP2
and
goes HIGH when V2MON exceeds V
TRIP2
. There is no power up reset delay circuitry on this pin.
V2 Voltage Monitor Input.
When the V2MON input is less than the V
TRIP2
voltage, V2FAIL goes
LOW. This input can monitor an unregulated power supply with an external resistor divider or can
monitor a second power supply with no external components. Connect V2MON to V
SS
or
V
CC
when
not used. The V2MON comparator is supplied by V2MON (X40030, X40031) or by the V
CC
input
(X40034, X40035).
Early Low V
CC
Detect.
This CMOS output signal goes LOW when
V
CC
< V
TRIP1
and goes high
when
V
CC
> V
TRIP1
.
No connect.
Manual Reset Input.
Pulling the MR pin LOW initiates a system reset. The RESET/RESET pin will
remain HIGH/LOW until the pin is released and for the t
PURST
thereafter.
RESET Output.
(X40031, X40035) This open drain pin is an active LOW output which goes LOW
whenever V
CC
falls below V
TRIP1
voltage or if manual reset is asserted. This output stays active
for the programmed time period (t
PURST
) on power up. It will also stay active until manual reset is
released and for t
PURST
thereafter.
RESET Output.
(X40030, X40034) This pin is an active HIGH CMOS output which goes HIGH
whenever V
CC
falls below V
TRIP1
voltage or if manual reset is asserted. This output stays active
for the programmed time period (t
PURST
) on power up. It will also stay active until manual reset is
released and for t
PURST
thereafter.
