Description for the DRV5055

The DRV5055 is a linear Hall effect sensor that respondsproportionally to magnetic flux density. The device can be used for accurate position sensing in awide range of applications.

The device operates from 3.3-V or 5-V power supplies. When no magnetic field is present,the analog output drives half of VCC. The output changes linearly with theapplied magnetic flux density, and four sensitivity optionsenable maximal output voltage swing based on the required sensing range. North and south magneticpoles produce unique voltages.

Magnetic flux perpendicular to the top of the package is sensed, and the two packageoptions provide different sensing directions.

The device uses a ratiometric architecture that can eliminate error fromVCC tolerance when the external analog-to-digital converter (ADC) uses thesame VCC for its reference. Additionally, the device features magnettemperature compensation to counteract how magnets drift for linear performance across a wide –40°Cto 125°C temperature range.Device options for no temperature compensation of magnet drift are alsoavailable.
