Product Description
Product Overview
The AH1806 is a high-sensitivity, micro-power Omnipolar Hall effect switch IC designed for portable, battery-powered consumer, home appliance, and industrial applications. It offers reliable performance across its operating range due to its sensitive Hall effect plates and copper-stabilized architecture. Optimized for low power consumption (24W at 3V), it operates from 2.5V to 5.5V and features a single open-drain output switchable by either North or South pole magnetic fields. Ideal for applications like smart-meter magnetic tamper detection, doors, lids, cover and tray position detection, and contactless switches.
