FEATURES  
DESCRIPTION  
„ Accurate under voltage system monitoring  
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.  
¯¯¯¯¯¯  
„ RESET guaranteed valid for VCC = 1.0V  
„ 6µA supply current  
„ 200ms RESET pulse width  
„ Watchdog timer function 1.6 sec timeout  
„ Brownout detection system reset for use with  
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.  
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  
¯¯¯¯¯¯  
The CAT705 and CAT706 provide a manual RESET  
input which initiate reset if pulled low. The CAT705,  
CAT706 and CAT813 provide a RESET output which  
is low for the CAT705 and CAT706, but high for the  
CAT813.  
„ Available in SOIC 8-lead and MSOP 8-lead  
packages  
APPLICATIONS  
„ Microprocessor and microcontroller based  
There is a secondary supply monitor included for  
power-fail warning (pin PFI).  
systems  
„ Intelligent instruments  
„ Control systems  
The CAT706 has a threshold voltage 4.40V. The  
CAT705/ CAT813 have a threshold voltage of 4.65V.
