3 Description
The DRV5021 device is a low-voltage, digital-switch,
Hall effect sensor for high-speed applications.
Operating from a 2.5-V to 5.5-V power supply, the
device senses magnetic flux density, and gives a
digital output based on predefined magnetic
thresholds.
This device senses magnetic fields perpendicular to
the face of the package. When the applied magnetic
flux density exceeds the magnetic operate point (BOP)
threshold, the open-drain output of the device drives
a low voltage. When the flux density decreases to
less than the magnetic release point (BRP) threshold,
the output goes to high impedance. The hysteresis
resulting from the separation of BOP and BRP helps
prevent output errors caused by input noise. This
configuration makes system designs more robust
against noise interference.
The device operates consistently across a wide
ambient temperature range of –40°C to +125°C.
