AIC812 General Description
AIC811/AIC812 are low-power microprocessor (P) supervisory circuits used to monitor power supplies in Pand digital systems. They provide applications with benefits of circuit reliability and low cost by eliminating external components. AIC811/AIC812 also offer a manual reset input.
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 AIC811 and AIC812 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 RESET output and active-high RESET output, respectively.
Low supply current (1A) makes AIC811/AIC812 ideal for portable equipment. The devices are available in SOT-23-5 package.
