AME8550

Voltage Detector

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.
