Linear Hall Effect Sensor responds proportionally to magnetic flux density. The device can be used for accurate position sensing in a wide range of applications. The DRV5055/DRV5055-Q1 operates from 3.3V or 5V power supplies. When no magnetic field is present, the analog output drives half of VCC. The output changes linearly with the applied magnetic flux density, and four sensitivity options enable maximal output voltage swing based on the required sensing range. North and south magnetic poles produce unique voltages. Magnetic flux perpendicular to the top of the package is sensed, and the two package options provide different sensing directions. The device uses a ratiometric architecture that can eliminate error from VCC tolerance when the external analog-to-digital converter (ADC) uses the same VCC for its reference. Additionally, the DRV5055/DRV5055-Q1 features magnet temperature compensation to counteract how magnets drift for linear performance across a wide –40°C to 125°C temperature range. The DRV5055-Q1 devices are AEC-Q100 qualified for automotive applications.
