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, and then the output goes to high impedance. The output current sink capability is 30 m A. A wide operating voltage range from 2.5 to 38 V with reverse polarity protection up...
