Nuances in ultra-low power designs for wearable products
With the ever-increasing functionality incorporated into the latest wearable devices, power management remains a key innovation area. Ultra-low power management is required to best operate activity trackers, smart watches, and audio-related devices. What does ultra-low power mean to these systems? For every wearable system, ultra-low power design requires careful consideration of quiescent current and shutdown current to achieve optimal power management architecture.
