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.
