The CAT809/810 protect µPs against brownout failure.
Short duration transients of 4µsec or less and 100 mV
amplitude typically do not cause a false RESET.
Figure 2 shows the maximum pulse duration of negative-
going V
DETAILED DESCRIPTIONS
RESET TIMING
The reset signal is asserted LOW for the CAT809 and
HIGH for the CAT810 when the power supply voltage
falls below the threshold trip voltage and remains asserted
for at least 140ms after the power supply voltage has
risen above the threshold.
