Product Overview
The AH180N is a high-sensitivity, micropower Omnipolar Hall-Effect switch IC designed for portable and battery-powered equipment. It offers reliable performance over its operating range due to its two sensitive Hall-Effect plates and chopper-stabilized architecture. Optimized for low power consumption (24A at 3V) and a wide supply range (2.5V to 5.5V), its single open-drain output activates with either a North or South magnetic pole. The output switches on when magnetic flux density exceeds the operate point (Bop) and turns off when it drops below the release point (Brp), remaining off in the absence of a magnetic field.
