CAT705, CAT706, CAT813
mP Supervisory Circuits
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
deviceâs specified trip value and then maintains the reset output active
condition until the deviceâs 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 MR input which 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 powerâfail
warning.
