MAX809 Series,  
MAX810 Series  
Very Low Supply Current  
3-Pin Microprocessor  
Reset Monitors  
The MAX809 and MAX810 are cost–effective system supervisor  
circuits designed to monitor VCC in digital systems and provide a reset  
signal to the host processor when necessary. No external components  
are required.  
The reset output is driven active within 10 µsec of VCC falling  
through the reset voltage threshold. Reset is maintained active for a  
minimum of 140 msec after VCC rises above the reset threshold. The  
MAX810 has an active–high RESET output while the MAX809 has  
an active–low RESET output. The output of the MAX809 is  
guaranteed valid down to VCC = 1.0 V. Both devices are available in a  
SOT–23 package.  
The MAX809/810 are optimized to reject fast transient glitches on  
the VCC line. Low supply current of 1.0 µA (VCC = 3.2 V) makes these  
devices suitable for battery powered applications.
