2.5V to 38V Hall Effect Omnipolar Switch Sensor - DRV5033

DRV5033 (ACTIVE)

2.5V to 38V Hall Effect Omnipolar Switch Sensor

 

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.
