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

BOP threshold, the device outputs 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 80Hz, 20Hz or 5Hz

for the lowest current consumption. Omnipolar and

unipolar magnetic responses are available.

The device operates from a VCC range of 1.65V to

5.5V, and is packaged in a standard SOT-23, TO-92

and small X2SON.
