Product Description

Product Overview

The AH9246 is an ultra-high sensitivity, micropower, omnipolar Hall-effect switch designed for battery-operated handheld and industrial applications. It features a chopper-stabilized architecture for improved magnetic switch point stability and a sleep-awake logic to reduce average current consumption. The output can be switched by either the north or south pole of a magnet. Available in TO92S and SC59 packages.
