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.
