The DRV5032 device is an ultra-low-power digital-switch Hall effect sensor, designed for the most compact and battery-sensitive systems. The device is offered in multiple magnetic thresholds, sampling rates, output drivers, and packages to accommodate various applications. ™

When the applied magnetic flux density exceeds the B_OP threshold, the device outputs a low voltage. The output stays low until the flux density decreases to less than B_RP, and then the output either drives a high voltage or becomes high impedance, depending on the device version. By incorporating an internal oscillator, the device samples the magnetic field and updates the output at a rate of 20 Hz, or 5 Hz for the lowest current consumption. Omnipolar and unipolar magnetic responses are available.

The device operates from a V_CC range of 1.65 V to 5.5 V, and is packaged in a standard SOT-23 and small X2SON.
