Rutronik adds Nordic Semiconductor’s PMIC

Offering efficient reliability in confined spaces, the Nordic nPM1100 is a dedicated power management IC (PMIC) with configurable dual-mode buck regulator and integrated battery charger. It is designed as a complementary component to Nordic‘s nRF52 and nRF53 series of SoCs and to ensure reliable power supply and stable operation while maximising battery life through high efficiency and low quiescent currents. It can also be used as a generic PMIC device, says Rutronik, which has added the nPM1100 to its portfolio.

Compact battery chargers are dedicated to charging in tight spaces

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.
