AME8550
Voltage Detector
n 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.
n Features
l Highly accurate: + 2%
l Low power consumption: TYP 0.8µA
(V =1.5V)
DD
l Detect voltage range: 1.6V to 6.0V in 0.1V
increments
l Operating voltage range: 1.2V to 6.5V
l Detect voltage temperature characteristics:
TYP ±100ppm/^oC
l Output configuration: N-channel open drain or
CMOS
l Ultra small package :
SOT-23 (150mW)
SOT-25 (150mW)
SOT-89 (500mW)
SC-70 (100mW)
l Add an external capacitor to perform an
µP reset.
n Applications
l Microprocessor reset circuitry
l Memory battery back-up circuits
l Power-on reset circuits
l Power failure detection
l System battery life and charge voltage
monitors
