The DRV5021A2QDBZR device is a low-voltage, digital-switch, Hall effectsensor for high-speedapplications. Operating from a2.5-V to 5.5-V power supply, the device senses magnetic flux density, and gives a digital outputbased on predefined magnetic thresholds.
This device senses magnetic fields perpendicular to the face of the package. When theapplied magnetic flux density exceeds the magnetic operate point (BOP)threshold, the open-drain output of the device drives a low voltage. When the flux densitydecreases to less than the magnetic release point (BRP) threshold, theoutput goes to high impedance. The hysteresis resulting from the separation ofBOP and BRP helps prevent output errors caused byinput 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.
