Negative-going V
The STM690A/692A/703/704/802/805/817/818/819 Supervisors are relatively immune to
negative-going V
reset comparator overdrive (for which the STM690A/692A/703/704/802/805/817/818/819
will NOT generate a reset pulse). The graph was generated using a negative pulse applied
to V
indicated (comparator overdrive). The graph indicates the maximum pulse width a negative
V
increases (further below the threshold), the maximum allowable pulse width decreases. Any
combination of duration and overdrive which lies under the curve will NOT generate a reset
signal. Typically, a V
or less will not cause a reset pulse. A 0.1 µF bypass capacitor mounted as close as possible
