3 Description

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

output stays low until the flux density decreases to

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.

5.5 V, and is packaged in a standard SOT-23 and

small X2SON.
