Product Description
Product Overview
The AH1802 is a high-sensitivity, micropower, omnipolar Hall Effect switch IC designed for portable and battery-powered equipment. It offers reliable performance over a wide operating range due to its sensitive Hall Effect plates and chopper-stabilized architecture. 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. The device is suitable for various detection applications, including open/close detection and cover/display switching.
