1 Introduction

Gaming controllers are a standard user interface that is often paired with gaming consoles like the Xbox, PlayStation, etc. These gaming controllers are rife with many different controls that include triggers, thumb sticks, buttons, and d-pads that all require sensors for converting the user’s mechanical input into an electrical stimulus. As these are ergonomically designed to fit in your hands, be portable, and remain powered on for extended periods of time, it is important to incorporate the most compact, power efficient sensing solutions as possible. This document will explore a variety of use cases for different low power modes pertaining to the sensors used in the gaming controllers.
