P0173 - As consumers find new ways to outfit their living spaces with simple-to-use smart home and Internet of Things (IoT) products, they may be unaware of certain vulnerabilities and security features.Learn More
AN296263 - The delay in a signal path can be described as the trail between the real-time angle and the displayed output angle. This delay represents the time needed to convert the magnetic field data sensed by the Hall plates into angle information.Learn More
AN296223 - The experiment results highlight several advantages of 3D Hall-effect sensors such as their ability to detect strong magnetic fields that are randomly applied to the outside of a smart home device.Learn More
AN296131 - In safety-critical magnetic sensing applications, such as torque sensing in electronic power steering (EPS) modules, redundant sensors are often the approach used to achieve desired performance while maintaining strict safety requirements.Learn More
Joysticks are widely used human-machine interfaces (HMI) that simultaneously report information on direction and amplitude. This document explains how to implement a 2D or 3D magnetic sensor to obtain a joystick with well-defined behavior.Learn More
AN296140 - This application note describes the use of the ALS31300 and ALS31313 3D Linear Hall-Effect Sensor integrated circuits (ICs) from Allegro MicroSystems for 3D linear sensing and 2D angle sensing applications.Learn More
AN296204 - This guide is intended to assist you in applying the A31315 Samples Programming Software to your short-stroke rotary application, such as a throttle-body, which uses the A31315 Advanced Linear Sensor and a target motion of 0° to 90°.Learn More
AN296201-This application note intends to describe the channel level errors and their impact on reported angle in 3D linear angle sensors when using the device in an on-axis rotary application. This document will also describe how to compensate for these errors using internal customer settings.Learn More
This paper introduces Hall-effect technology, then explores how it has been applied, in particular, differentiating between the primary types of Hall sensor ICs and the highly differentiated range of sensing behaviors they can support.Learn More
