General Description
The AME8550 series are highly precise, low power con-
sumption voltage detectors, manufactured using CMOS
and fuse trimming technologies. Detect voltage is ex-
tremely accurate with minimal temperature drift.
Both CMOS and N channel open drain output configu-
rations are available.
