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.
Application Note
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.

Combining our proven planar and vertical Hall technologies, 3DMAG solutions offer robust, high-performing, three-axis magnetic field measurements in a single IC.
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.
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.
AN296189 - The A31315 is a multi-axis Halleffect sensor with advanced integrated signal processing capabilities that simplifies the numerous design challenges that the systems designer faces.
AN296260 - This application note describes procedures for programming the A31315 DLL using MATLAB on Windows OS.
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°.
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.
AN296229 - The Allegro 3D magnetic sensing devices can be used in a wide range of applications where mechanical motion (linear or rotational) can be expressed by a changing magnetic angle. Read More.
A recent breakthrough in Hall-effect sensing has enabled the creation of omnidirectional magnetic sensor ICs that match all of the requirements for tamper detection.
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.
In this application note we are investigating how to extend the displacement range for linear detection by using two sensor ICs, using typical Allegro™ MicroSystems devices as examples.
The conventional signal demodulator of a chopper amplifier can be substituted by track-and-hold (T/H) and averaging functions. This arrangement provides offset cancellation without requiring low-pass filters and can ignore the residual offset generated by input spikes.
Many applications in different industries, such as in industrial automation and automotive sensors and actuators, require monitoring the angle of a rotating shaft either in an on-axis or off-axis arrangement. This application note is dedicated to a review of on-axis magnetic applications.
