3 Description

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, 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.
