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 B_OP
threshold, the DRV5033-Q1 open-drain output goes
low. The output stays low until the field decreases to
less than B_RP, 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.
