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 repeated-
ly 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 watch-
dog (
WDO
) output to signal that the system is not exe-
cuting 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 watch-
dog 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.
