DESCRIPTION
The UTC 81CXXX and 81NXXX series are good
SOT-89
TO-92
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.
