描述 Description

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.FEATURES
■ Accurate under voltage system monitoring

■ Watchdog timer function 1.6 sec timeout
■ Brownout detection system reset for use with 3.0, 3.6, and 5.0 volt systems
■ Pin and function compatible with the MAX705/706/813L products
■ Operating Range from -40°C to +85°C
■ Available in SOIC 8-lead and MSOP 8-lead packagesAPPLICATIONS
■ Microprocessor and microcontroller based systems
■ Intelligent instruments
■ Control systems
■ Critical µP monitors
■ Portable equipment
