The UTC
81CXX
and
81NXX
series are good performance
voltage detector and manufactured by CMOS technologies with
highly accurate, low power consumption. A delay circuit is built-in
to each detector, therefore, peripherals are unnecessary and high
density mounting is possible. Detect voltage is extremely accurate
with minimal temperature drift. Both CMOS and N-channel open
drain output configurations are available.
