MAX6316–MAX6322

5-Pin μP Supervisory Circuits with

Watchdog and Manual Reset

Figure 10 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 a reset or interrupt to be issued. As

described in the Watchdog Input Current section, this

scheme results in higher time average WDI current than

does leaving WDI low for the majority of the timeout

period and periodically pulsing it low-high-low.
