Build with DRV5055 — Datasheet Specs & AI Design Help

00 — Overview

What the DRV5055 does

The DRV5055 is a ratiometric linear Hall effect sensor that responds proportionally to magnetic flux density. It operates from 3.3-V or 5-V power supplies and offers four sensitivity options ranging from 12.5 mV/mT to 100 mV/mT with corresponding output ranges. The device features a 20-kHz sensing bandwidth, low noise with ±1-mA drive capability, and built-in compensation for magnet temperature drift. Standard packages include SOT-23 and TO-92. Designers typically use this component for precise position sensing, industrial automation, robotics, home appliances, gamepads, tilt measurement, fluid flow rate monitoring, medical devices, and current sensing applications.
