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 devices have a watchdog input which can be
¯¯¯¯
used to monitor a system signal and causes WDO to
go low if the signal fails to change state prior to a
timeout condition.
The supervisory circuits provide a ¯¯¯ input which
MR
initiates a reset if pulled low. The CAT705 and
¯¯¯¯¯¯
CAT706 provide an active low RESET output. The
CAT813 provides an active high RESET output.
There is a secondary supply monitor (PFI) included for
power-fail warning.
