3 Description
The DRV5056-Q1 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 –
40°C to +150°C temperature range.
