3 Description

The DRV5033-Q1 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-Q1 responds the same to both

polarities of magnetic field direction. When the

applied magnetic flux density exceeds the BOP

threshold, the DRV5033-Q1 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 2.7 to 38 V

with reverse polarity protection up to –22 V makes

the device suitable for a wide range of automotive

applications.

Internal protection functions are provided for reverse

supply conditions, load dump, and output short circuit

or over current.
