DETAILED DESCRIPTIOnS
RESET TIMInG
The reset signal is asserted LOW for the CAT803/
CAT809 and HIGH for the CAT80 when the power
supply voltage falls below the threshold trip voltage and
remains asserted for at least 40ms after the power
supply voltage has risen above the threshold.
V
The CAT803/CAT809/CAT80 protect µPs against
brownout failure. Short duration transients of 4µsec
or less and 00mV amplitude typically do not cause a
false RESET.
