General Description
The MAX6369–MAX6374 are pin-selectable watchdog
timers that supervise microprocessor (μP) activity and
signal when a system is operating improperly. During
normal operation, the microprocessor should repeatedly
toggle the watchdog input (WDI) before the selected
watchdog timeout period elapses to demonstrate that
the system is processing code properly. If the μP does
not provide a valid watchdog input transition before the
timeout period expires, the supervisor asserts a watchdog
(WDO) output to signal that the system is not executing
the desired instructions within the expected time frame.
The watchdog output pulse can be used to reset the μP or
interrupt the system to warn of processing errors.
The MAX6369–MAX6374 are flexible watchdog timer
supervisors that can increase system reliability through
notification of code execution errors. The family offers
several pin-selectable watchdog timing options to match
a wide range of system timing applications:
● Watchdog startup delay: provides an initial delay
before the watchdog timer is started.
● Watchdog timeout period: normal operating watchdog
timeout period after the initial startup delay.
● Watchdog output/timing options: open drain (100ms)
or push-pull (1ms).
The MAX6369–MAX6374 operate over a +2.5V to +5.5V
supply range and are available in miniature 8-pin SOT23
packages.

Detailed Description
The MAX6369–MAX6374 are flexible watchdog circuits
for monitoring μP activity. During normal operation, the
internal timer is cleared each time the μP toggles the
WDI with a valid logic transition (low to high or high to
low) within the selected timeout period (tWD). The WDO
remains high as long as the input is strobed within the
selected timeout period. If the input is not strobed before
the timeout period expires, the watchdog output is asserted
low for the watchdog output pulse width (tWDO). The
device type and the state of the three logic control pins
(SET0, SET1, and SET2) determine watchdog timing
characteristics. The three basic timing variations for the
watchdog startup delay and the normal watchdog timeout
period are summarized below (see Table 1 for the timeout
characteristics for all devices in the family):
● Watchdog Startup Delay:
Provides an initial delay before the watchdog timer is
started.
Allows time for the μP system to power up and initialize
before assuming responsibility for normal watchdog
timer updates.
Includes several fixed or pin-selectable startup delay
options from 200μs to 60s, and an option to wait for
the first watchdog input transition before starting the
watchdog timer.

● Watchdog Timeout Period:
Normal operating watchdog timeout period after the
initial startup delay.
A watchdog output pulse is asserted if a valid watch-
dog input transition is not received before the timeout
period elapses.
Eight pin-selectable timeout period options for each
device, from 30μs to 60s.
Pin-selectable watchdog timer disable feature.
● Watchdog Output/Timing Options:
Open drain, active low with 100ms minimum watchdog
output pulse (MAX6369/MAX6371/MAX6373).
Push-pull, active low with 1ms minimum watchdog
output pulse (MAX6370/MAX6372/MAX6374).
Each device has a watchdog startup delay that is initiated
when the supervisor is first powered or after the user
modifies any of the logic control set inputs. The watch-
dog timer does not begin to count down until the
completion of the startup delay period, and no watchdog
output pulses are asserted during the startup delay. When
the startup delay expires, the watchdog begins counting its
normal watchdog timeout period and waiting for WDI transitions.
The startup delay allows time for the μP system to power
up and fully initialize before assuming responsibility for the
normal watchdog timer updates. Startup delay periods vary
between the different devices and may be altered by the
logic control set pins. To ensure that the system generates
no undesired watchdog outputs, the routine watchdog input
transitions should begin before the selected minimum startup
delay period has expired.
The normal watchdog timeout period countdown is initiated
when the startup delay is complete. If a valid logic transition
is not recognized at WDI before the watchdog timeout
period has expired, the supervisor asserts a watchdog
output. Watchdog timeout periods vary between the different
devices and may be altered by the logic control set pins.
To ensure that the system generates no undesired watch-
dog outputs, the watchdog input transitions should occur
before the selected minimum watchdog timeout period
has expired.
The startup delay and the watchdog timeout period are
determined by the states of the SET0, SET1, and SET2
pins, and by the particular device within the family. For
the MAX6369 and MAX6370, the startup delay is equal
to the watchdog timeout period. The startup and watch-
dog timeout periods are pin selectable from 1ms to 60s
(minimum).
For the MAX6371 and MAX6372, the startup delay is fixed
at 60s and the watchdog timeout period is pin selectable
from 1ms to 60s (minimum).
The MAX6373/MAX6374 provide two timing variations
for the startup delay and normal watchdog timeout. Five
of the pin-selectable modes provide startup delays from
200μs to 60s minimum, and watchdog timeout delays
from 3ms to 10s minimum. Two of the selectable modes

do not initiate the watchdog timer until the device receives
its first valid watchdog input transition (there is no fixed
period by which the first input must be received). These
two extended startup delay modes are useful for applications
requiring more than 60s for system initialization.
All the MAX6369–MAX6374 devices may be disabled with
the proper logic control pin setting (Table 1).
Applications Information
Input Signal Considerations
Watchdog timing is measured from the last WDI rising
or falling edge associated with a pulse of at least 100ns
in width. WDI transitions are ignored when WDO is
asserted, and during the startup delay period (Figure 1).
Watchdog input transitions are also ignored for a setup
period, tSETUP, of up to 300μs after power-up or a setting
change (Figure 2).
Selecting Device Timing
SET2, SET1, and SET0 program the startup delay and
watchdog timeout periods (Table 1). Timeout settings
can be hard wired, or they can be controlled with logic
gates and modified during operation. To ensure smooth
transitions, the system should strobe WDI immediately
before the timing settings are changed. This minimizes
the risk of initializing a setting change too late in the timer
countdown period and generating undesired watchdog
outputs. After changing the timing settings, two outcomes
are possible based on WDO. If the change is made while
WDO is asserted, the previous setting is allowed to finish, the
characteristics of the new setting are assumed, and the
new startup phase is entered after a 300μs setup time
(tSETUP) elapses. If the change is made while WDO is not
asserted, the new setting is initiated immediately, and the
new startup phase is entered after the 300μs setup time
elapses.
Selecting 011 (SET2 = 0, SET1 = 1, SET0 = 1) disables
the watchdog timer function on all devices in the family.
Operation can be reenabled without powering down by
changing the set inputs to the new desired setting. The
device assumes the new selected timing characteristics
and enter the startup phase after the 300μs setup time
elapses (Figure 2). WDO is high when the watchdog timer
is disabled.
The MAX6373/MAX6374 offer a first-edge feature. In first-
edge mode (settings 101 or 110, Table 1), the internal timer
does not control the startup delay period. Instead, startup
terminates when WDI sees a transition. If changing to first-
edge mode while the device is operating, disable mode
must be entered first. It is then safe to select first-edge
mode. Entering disable mode first ensures the output is
unasserted when selecting first-edge mode and removes
the danger of WDI being masked out.
Output
The MAX6369/MAX6371/MAX6373 have an active-low,
open-drain output that provides a watchdog output pulse
of 100ms. This output structure sinks current when WDO
is asserted. Connect a pullup resistor from WDO to any
supply voltage up to +5.5V.
Select a resistor value large enough to register a logic
low (see Electrical Characteristics), and small enough
to register a logic high while supplying all input current
and leakage paths connected to the WDO line. A 10kΩ
pullup is sufficient in most applications. The MAX6370/
MAX6372/MAX6374 have push-pull outputs that provide
an active-low watchdog output pulse of 1ms. When WDO
deasserts, timing begins again at the beginning of the
watchdog timeout period (Figure 1).

Usage in Noisy Environments
If using the watchdog timer in an electrically noisy envi-
ronment, a bypass capacitor of 0.1μF should be con-
nected between VCC and GND as close to the device as
possible, and no further away than 0.2 inches.
Watchdog Software
Considerations
To help the watchdog timer monitor software execution
more closely, set and reset the watchdog input at different
points in the program, rather than pulsing the watchdog
input high-low-high or low-high-low. This technique avoids
a stuck loop, in which the watchdog timer would continue
to be reset inside the loop, keeping the watchdog from
timing out. Figure 3 shows an example of a flow diagram
where the I/O driving the watchdog input is set high at
the beginning of the program, set low at the end of every
subroutine or loop, then set high again when the program
returns to the beginning. If the program should hang in
any subroutine, the problem would be quickly corrected,
since the I/O is continually set low and the watchdog timer
is allowed to time out, causing WDO to pulse.
