The DRV5056 is a linear Hall effect sensor that responds proportionally to flux density of a magnetic south pole. The device can be used for accurate position sensing in a wide range of applications.

Featuring a unipolar magnetic response, the analog output drives 0.6 V when no magnetic field is present, and increases when a south magnetic pole is applied. This response maximizes the output dynamic range in applications that sense one magnetic pole. Four sensitivity options further maximize the output swing based on the required sensing range.

The device operates from 3.3-V or 5-V power supplies. 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 minimize error from VCC tolerance when the external analog-to-digital converter (ADC) uses the same VCC for its reference. Additionally, the device features magnet temperature compensation to counteract how magnets drift for linear performance across a wide temperature range. Device options for no temperature compensation of magnet drift are also available.

The A1 to A4 options support a temperature range of –40°C to +125°C. The A6 version supports a temperature range of 0°C to 85°C.
