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.
