Detailed Descriptions
Reset Timing
The reset signal is asserted LOW for the CAT803/CAT809 and HIGH for the CAT810 when the power supply voltage falls below
the threshold trip voltage and remains asserted for at least 140 ms after the power supply voltage has risen above the threshold.

Transient Response
The CAT803/CAT809/CAT810 protect mPs against
brownout failure. Short duration transients of 4 msec or less
and 100 mV amplitude typically do not cause a false RESET.
Figure 7 shows the maximum pulse duration of negative−
going V
CC
transients that do not cause a reset condition.
As the amplitude of the transient goes further below the
threshold (increasing V
TH
− V
CC
), the maximum pulse
duration decreases. In this test, the V
CC
starts from an initial
voltage of 0.5 V above the threshold and drops below it by
the amplitude of the overdrive voltage (V
TH
− V
CC
).
