The DRV5032FDDMRT device is an ultra-low-power digital-switch Hall effect sensor, designed forthe most compact and battery-sensitive systems. The device is offered in multiple magneticthresholds, sampling rates, output drivers, and packages to accommodate variousapplications.
When the applied magnetic flux density exceeds the BOP threshold,the device outputs a low voltage. The output stays low until the flux density decreases to lessthan BRP, and then the output either drives a high voltage or becomes highimpedance, depending on the device version. By incorporating an internal oscillator, the devicesamples the magnetic field and updates the output at a rate of 20 Hz, or 5 Hz for the lowestcurrent consumption. Omnipolar and unipolar magnetic responses are available.
The device operates from a VCC range of 1.65 V to 5.5 V, and ispackaged in a standard SOT-23 and small X2SON.
