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 0.6V 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. Multiple sensitivity options further maximize the output swing based on the required sensing range.
The device operates from 3.3V or 5V 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 the reference. Additionally, the device features magnet temperature compensation to counteract how magnets drift for linear performance across a wide –40°C to +125°C temperature range. Device options for no temperature compensation of magnet drift are also available.

HALL-PROXIMITY-DESIGN is a software tool that facilitates rapid iterative design for magnet and Hall-effect sensor systems.
This reference design uses Hall-effect sensors to implement a trigger that outputs varying voltage based on how far the trigger is pressed. These types of triggers are useful in cordless power tools or any other end equipment that uses trigger displacement information.
The design uses a contactless (...)
