■General Description
The XC61F series are highly accurate, low power consumption voltage
detectors, manufactured using CMOS and laser trimming technologies. A
delay circuit is built-in to each detector.
Detect voltage is extremely accurate with minimal temperature drift.
Both CMOS and N-channel open drain output configurations are
available.
Since the delay circuit is built-in, peripherals are unecessary and high
density mounting is possible.
