7.1 Overview

The DRV5021 device is a spinning-current Hall sensor with a digital output for magnetic-sensing applications. The DRV5021 can be powered with a supply voltage between 2.5 V and 5.5 V.

The field polarity is defined as follows: a south pole near the marked side of the package is a positive magnetic field. A north pole near the marked side of the package is a negative magnetic field. The output state depends on the magnetic field perpendicular to the package.

A strong south pole near the marked side of the package causes the output to pull low. A weak south pole, the absence of a field, or any north pole makes the output high impedance. Hysteresis is included in between the operate point and the release point to prevent toggling near the magnetic threshold.

An external pullup resistor is required on the OUT pin. The OUT pin can be pulled up to VCC, or to a different voltage supply. This feature allows for easier interfacing with controller circuits.
