7 Detailed Description

7.1 Overview

The DRV5055 is a 3-pin linear Hall effect sensor with fully integrated signal conditioning, temperature

compensation circuits, mechanical stress cancellation, and amplifiers. The device operates from 3.3-V and 5-V

(±10%) power supplies, measures magnetic flux density, and outputs a proportional analog voltage that is
