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 V_CCsupply voltage falls below

preset threshold then a reset signal is asserted for at least 140ms after V_CChas risen above the

reset threshold. Both the SP809 and SP810 were designed with a reset 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.
