MAX6730–MAX6735
Overdrive, for which reset pulses are not generated.
The graph was produced using falling VCC_ pulses,
starting above VTH and ending below the reset thresh-
old by the magnitude indicated (reset threshold over-
drive). The graph shows the maximum pulse width that
a falling VCC transient typically might have without
causing a reset pulse to be issued. As the amplitude of
the transient increases (i.e., goes further below the
reset threshold), the maximum allowable pulse width
decreases. A 0.1F bypass capacitor mounted close to
VCC_ provides additional transient immunity.
Watchdog Software Considerations
Setting and resetting the watchdog input at different
points in the program rather than “pulsing” the watch-
dog input high-low-high or low-high-low helps the
watchdog timer closely monitor software execution.
This technique avoids a “stuck” loop, in which the
watchdog timer continues to be reset within the loop,
preventing the watchdog from timing out. Figure 6
shows an example flow diagram in which the I/O dri-
ving the watchdog input is set high at the beginning of
the program, set low at the beginning of every subrou-
tine or loop, and then set high again when the program
returns to the beginning. If the program “hangs” in any
subroutine, the I/O continually asserts low (or high),
and the watchdog timer expires, issuing a reset or
interrupt.
