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
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, TO-92
and small X2SON.
