7 Detailed Description

7.1 Overview

The DRV5023-Q1 device is a chopper-stabilized Hall sensor with a digital output for magnetic sensing

applications. The DRV5023-Q1 device can be powered with a supply voltage between 2.7 and 38 V, and will

survive –22 V reverse-battery conditions. The DRV5023-Q1 device does not operate when –22 to 2.4 V is

for transient durations.
