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
B_OP threshold, the device output drives 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 dual-
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.
