DRV5023 - Texas Instruments

DRV5023 Digital-Switch Hall Effect Sensor

The DRV5023 device is a chopper-stabilized Hall Effect Sensor that offers a magnetic sensing solution with superior sensitivity stability over temperature and integrated protection features. When the applied magnetic flux density exceeds the BOP threshold, the DRV5023 open-drain output goes low. The output stays low until the field decreases to less than BRP.
