AT121 - Micro-Power Voltage Detector

General Description

The AT121 series are highly accurate and ultra low power consumption voltage detectors.

It offers internally fixed threshold levels with 0.05V per step range from 1.2V to 5V.

A time delay circuit can be accomplished with the addition of an external capacitor.

Key Features

  • High Accuracy：± 2% Low Power Consumption：1.0µA(TYP. ) at VIN =2.0V Detect Voltage Range：1.2V ~ 5V in 0.05V step Operating Voltage Range：1V ~ 6V Detect Voltage Temperature Characteristics： ±100ppm/°c Output Configuration：N-channel open drain or CMOS Packages：SOT-25, SOT-343, SOT-89, TO-92 Immense Advance Tech.
