The DRV5056-Q1 device is a linear Hall effect sensor that responds
proportionally to magnetic flux density. 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
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 –40°C
to +150°C temperature range.
