As wearable, medical and smart sensor products use streamlined power management for energy harvesting hardware, e-peas has developed a family of battery charger devices, dedicated to charging. The company’s existing power management ICs (PMICs) offer direct power delivery to the application, as well as the charging of energy storage elements (such as Li-Ion batteries or super capacitors), but the AEM10900, AEM10300 and AEM30300 are fully dedicated to the charging function. This allows them to be used where a simpler implementation can be used and where there are space or cost constraints.

Glitch-free supervisor offers robust protection for low voltage IoT applications
Claimed to be the industry’s smallest, lowest power, glitch-free supervisor, the MAX16162 eliminates power-up errors, claims Maxim Integrated.
Nordic introduces first PMIC for tight spaces
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.
