Description

Well-designed electronic systems only use as much power as they need to for each state of operation. While this is crucial for battery-powered systems, AC powered systems also benefit from minimizing power, since that reduces heat dissipation, maximizes the product lifetime, and conserves electricity.

Low-power modes work best when they seamlessly transition to a higher power mode without the user taking separate action. This full automation will be paramount to smart systems of the future. When the power mode can change based on some mechanical movement occurring, Hall effect sensors are often a suitable technology to be used.
