3 Description

The DRV5033 device is a chopper-stabilized Hall

Effect Sensor that offers a magnetic sensing solution

with superior sensitivity stability over temperature and

integrated protection features.

The DRV5033 responds the same to both polarities

of magnetic field direction. When the applied

magnetic flux density exceeds the BOP threshold, the

DRV5033 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 mA. A wide

operating voltage range from 2.5 to 38 V with reverse

polarity protection up to –22 V makes the device

suitable for a wide range of industrial applications.

Internal protection functions are provided for reverse

supply conditions, load dump, and output short circuit

or over current.
