Processor Supervisor 2.944V 3-Pin SOT-23 T/R
AIC809N is a 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. These devices perform as valid singles in applications with Vcc ranging from 6.0V down to 0.9V. The reset signal lasts for a minimum period of 140ms whenever VCC supply voltage falls below preset threshold. Both AIC809N were designed with a reset comparator to help identify invalid signals, which last less than 140ms. The only difference between them is that they have an active-low output and active-high RESET output, respectively. Low supply current (1μA) makes AIC809N ideal for portable equipment. The devices are available in SOT-23 package.
