MAX705-MAX813L  
Low-Cost, µP Supervisory Circuit  
General Description  
The MAX705-MAX708/MAX813L microprocessor (µP)  
supervisory circuits reduce the complexity and number of  
components required to monitor power-supply and battery  
functions in µP systems. These devices significantly improve  
system reliability and accuracy compared to separate ICs or  
discrete components.  
Applications  
z Computers  
z Controllers  
z Intelligent Istruments  
z Automotive Systems  
z Critical µP Power Monitoring  
The MAX705/MAX706/MAX813L provide four functions:  
1)A reset output during power-up, power-down, and brownout  
conditions.  
2) An independent watchdog output that goes low if the  
watchdog input has not been toggled within 1.6 seconds.  
3)A 1.25V threshold detector for power-fail warning,  
low-battery detection, or for monitoring a power supply other  
than +5V.  
Features  
z µMAX Package: Smallest 8-Pin SO  
z Guaranteed RESET Valid at Vcc=1V  
z Precision Supply-Voltage Monitor  
4.65V in MAX705/MAX707/MAX813L  
4.40V in MAX706/MAX708  
z 200ms Reset Pulse Width  
4) An active-low manual-reset input.  
z Debounced TTL/CMOS-Compatible Manual-Reset Input  
The MAX707/MAX708 are the same as the MAX705/MAX706,  
except an active-high reset is substituted for the watchdog  
timer. The MAX813L is the same as the MAX705, except  
RESET is provided instead of RESET.  
z Independent Watchdog Timer  
1.6sec Timeout  
(MAX705/MAX706)  
z Active-high Reset Output (MAX707/MAX708/MAX813L)  
z Voltage Monitor for Power-Fail or Low-Battery Warning  
Two supply-voltage monitor levels are available: The  
MAX705/MAX707/MAX813L generate a reset pulse when the  
supply  
voltage  
drops  
below  
4.65V,  
while  
the  
MAX706/MAX708 generate a reset pulse below 4.40V. All four  
parts are available in 8-pin DIP, SO and µMAX packages.
