3 Description

The DRV5023-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.

When the applied magnetic flux density exceeds the

goes low. The output stays low until the field

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.
