DESCRIPTION
AIC809/AIC810 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.
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
V
CC supply voltage falls below preset threshold. Both
AIC809 and AIC810 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
active-high RESET output, respectively.
