DESCRIPTION
The CAT705, CAT706, and CAT813 provide reset and
monitoring functions for the electronic systems. Each
device monitors the system voltage and maintains a
reset output until that voltage reaches the device’s
specified trip value and then maintains the reset
output active condition until the device’s internal timer
allows the system power supply to stabilize.
The CAT705, CAT706, and CAT813 have a watchdog
input which can be used to monitor a system signal
and cause a reset to be issued if the signal fails to
change state prior to a timeout condition.
¯¯¯¯¯¯
The CAT705 and CAT706 provide a manual RESET
input which initiate reset if pulled low. The CAT705,
CAT706 and CAT813 provide a RESET output which
is low for the CAT705 and CAT706, but high for the
CAT813.
There is a secondary supply monitor included for
power-fail warning (pin PFI).
The CAT706 has a threshold voltage 4.40V. The
CAT705/ CAT813 have a threshold voltage of 4.65V.
