The DRV5021-Q1 device is a low-voltage, digital-switch, Hall effect
sensor for high-speed automotive 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
+150°C.
