ADM8641 - Ultralow Power Voltage Detector

📥 Download Datasheet

General Description

The ADM8641 and ADM8642 are simple voltage detectors suitable for use in general-purpose applications.

The ultralow power consumption of these devices makes them suitable for power efficiency sensitive systems, such as battery-powered portable devices and energy meters.

The factory preset detection thresholds from 0.5 V to 4.63 V with ±1.2% accuracy over the full temperature range enable the devices to monitor the node of interest accurately with direct contact.
