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.

FEATURES

■ Reset guaranteed valid for 1.0 V VCC

■ 6μA supply current

■ Watchdog timer function 1.6s timeout

■ Accurate brownout detection reset in 3.0, 3.6, and 5.0 volt systems

■ Secondary low supply monitoring on PFI input

■ Pin and function compatible with the MAX705/MAX706/MAX813L products

■ Operating Range from -40°C to +85°C

■ RoHS Compliant SOIC 8-lead and MSOP 8-lead packages

APPLICATIONS

■ Microprocessor and microcontroller based systems

■ Instrument and control systems

■ Portable equipment
