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 sampling rates, output drivers, and
packages to accommodate various applications.
When the applied magnetic flux density exceeds the
BOP threshold, the device output drives a low voltage.
The output stays low until the flux density decreases
to less than BRP, 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 dual-
unipolar magnetic responses are available.
The device operates from a VCC range of 1.65 V to
5.5 V, and is packaged in a standard SOT-23 and
small X2SON.
