7 Detailed Description

7.1 Overview

The DRV5032 device is a magnetic sensor with a digital output that indicates when the magnetic flux density

threshold has been crossed. The device integrates a Hall effect element, analog signal conditioning, and a

low-frequency oscillator that enables ultra-low average power consumption. By operating from a 1.65-V to 5.5-V

supply, the device periodically measures magnetic flux density, updates the output, and enters a low-power

sleep state.
