Product Description
Product Overview
The AH1802 is a micropower, ultra-sensitive omnipolar Hall-effect sensor switch designed for portable and battery-powered devices. It offers reliable performance across a wide operating range due to its chopper-stabilized architecture and sensitive Hall Effect plates. Optimized for low power consumption (24W at 3V), it features a single open-drain output that switches ON with either a north or south magnetic pole. Ideal for applications requiring contactless switching and detection.
