Design Considerations
There is a balance to be struck between ultra-long battery life and always-on functionality-energy efficiency is very important
Low power consumption is essential for these small wearable devices
Requires very small package or wafer-level chip occupation area
For more energy-efficient wired charging, you can use two back-to-back mosfets instead of built-in Schottky diode.”
