Diodes Inc. – AH9246, AH9250 and AH9251: Ultra-High to Medium-Sensitivity Micropower, Omnipolar Hall Effect Switches

AH9246, AH9250 and AH9251 are ultra-high to medium sensitivity, micropower, omnipolar, hall effect switch ICs, designed for portable and battery-powered consumer equipment, home appliances and industrial applications. Based on a single hall plate and chopper-stabilized architecture, AH9246, AH9250 and AH9251 provide reliable solutions over the whole operating range. Also, this family of hall effect switch ICs have push-pull output structures, therefore an external pull up resistor is not required.
