PMP11311.1, Power Reference Design for a Wearable Device with Wireless Charging using the bq51003 and bq25120. Wearable devices require advanced power management to achieve long battery run times with always-on functionality. The devices need to use small rechargeable batteries and enable small footprint designs. This application note shows the implementation of a scalable power management solution for wearables that can be tailored for activity monitors or smart watches. The design provides a wireless charging input, highly configurable battery management solution with Li-Ion battery charger and low quiescent current (Iq) DC/DC buck, boost converter for PMOLED display, boost converter for Heart Rate Monitor (HRM) and second configurable low Iq DC/DC buck
