Nordic Semiconductor’s first power management device is the nPM1100, a power management integrated circuit (PMIC). It combines a USB compatible Li-ion/Li-Po battery charger and DC/DC buck regulator in a compact WLCSP for space-constrained applications.

Dialog Semiconductor uses low power flash memory to increase hearable lifetimes
Reducing the footprint of a hearable device, such as an ear bud, by using smaller batteries can come at the cost of shorter runtimes between recharges, advises Dialog Semiconductor. Hearable devices frequently read data to support advanced functionality such as connectivity, auto-pairing, charge cradle data exchange and equalisation. Dialog Semiconductor has developed the AT25SL128A Flash to minimise power consumption. It features low power, 1.8 V operation, fast read, low profile wafer level chip scale packages (WLCSPs) and is intended for small IoT devices like hearables.
NuCurrent cuts loose by extending HF wireless charging
For product categories that are using RF and inductive charging, NuCurrent has launched NuEva (high frequency) HF development platform based on inductive resonant power transfer.
InnovationLab and Evonik partner for printed rechargeable batteries
Printed electronics specialist, InnovationLab has partnered with chemical company, Evoknik to develop the fully printed, flexible, rechargeable, solid-state batteries. The batteries, which combine Evonik’s TAeTTOOz printable battery materials and InnovationLab’s high-speed printed electronics capability results in thin printed batteries that are more flexible, safer and more environmentally friendly than traditional metal-based batteries.
