5 Summary

Magnetic position sensors are a viable low power design for designing controls like thumb sticks and triggers found in gaming controllers and VR controllers. Features like enable pins not only help increase efficiency, but reduce device count, free up board space, and allow a single ADC to monitor multiple devices. Diverse operating modes for devices like the TMAG5273 and TMAG3001 provide the user with multiple methods of reducing device power consumption while providing flexibility for different signal chain setups.
