General Description
The MLX90248 Omnipolar TM Hall effect sensor technology. It incorporates advanced chopper-stabilization techniques to provide accurate and stable magnetic switch points.
The circuit design provides an internally controlled clocking mechanism to cycle power to the Hall element and analog signal processing circuits.

Features and Benefits
◾ Micropower consumption ideal for batterypowered applications
◾ Omnipolar, easy to use as output switches with both North and South pole
◾ Very High Sensitivity Hall Sensor
◾ Chopper stabilized amplifier stage
◾ Open-Drain Output
◾ Operation down to 1.5V
◾ Ultra-Thin QFN package (0.43mm max) & Thin SOT23 3L (both RoHS Compliant)

Applications
◾ Solid State Switch
◾ Handheld Wireless Handset Awake Switch
◾ Lid close sensor for battery-powered devices
◾ Magnet proximity sensor for reed switch replacement in low duty cycle applications
◾ Energy metering
