Texas Instruments PDRV5056A1EDBZTQ1
The DRV5056-Q1 is a linear Hall effect sensor that respondsproportionally to flux density of a magnetic south pole. The device can be used for accurateposition sensing in a wide range of applications.
Featuring a unipolar magnetic response, the analog output drives 0.6 V when no magneticfield is present, and increases when a south magnetic pole is applied. This response maximizes theoutput dynamic range in applications that sense one magnetic pole. Four sensitivity options furthermaximize 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 thetop of the package is sensed, and the two package options provide different sensingdirections.
The device uses a ratiometric architecture that can minimize 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 +150°C temperaturerange.
