DESCRIPTION  
The SP809/SP810 are low power microprocessor (µP) supervisory circuits used to monitor  
power supplies in µP and digital systems. They provide applications with benefits of circuit  
reliability and low cost by eliminating external components. If the VCC supply voltage falls below  
preset threshold then a reset signal is asserted for at least 140ms after V has risen above the  
reset threshold. Both the SP809 and SP810 were designed with a reseCCt comparator to help  
identifyinvalidsignals, whichlastlessthan140ms. Theonlydifferencebetweenthemisthatthey  
have an active-low RESET output and active-high RESET output, respectively. Low supply  
current (1µA) makes SP809/SP810 ideal for portable equipment. The devices are available in  
3 pin SOT-23 package.
