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 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 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.
