Versatile and simple contactless switch solutions suit multiple applications

Available now from Digi-Key stock, Diodes' AH9246, AH9250, and AH9251 are integrated, yet small, simple and flexible contactless switch solution options suitable for multiple applications The ultra-high to medium-sensitivity, micropower, omnipolar, Hall-effect switch ICs are designed for portable and battery-powered consumer equipment, home appliances, and industrial applications. Based on a single Hall plate and chopper-stabilized architecture, they provide reliable solutions over the whole operating range. This family of Hall-effect switches is optimized to operate over the supply range of 2.5V to 5.5V and incorporates a micropower sleep function to give an average supply current of only 8µA. AH9246, AH9250, and AH9251 have push-pull output structures; therefore, an external pull-up resistor is not required. They are available in industry-standard SC59 and TO92S packages.
