Nordic Semiconductor has introduced the nPM2100 power management IC (PMIC) to optimize power efficiency and system performance in non-rechargeable battery applications. Since its launch in January, early adopters have integrated it into products ranging from personal health monitors to wireless industrial sensors. Now, all developers can leverage its advanced capabilities to enhance their designs.

The nPM2100 offers power-saving and system management features that surpass basic regulators, enabling more efficient power solutions. For small wireless IoT applications, it extends battery life or allows the use of smaller batteries for compact designs. Key energy-saving features include a 35nA shipping mode with multiple wake-up options, a sleep mode consuming less than 200nA with timer wake-up adjustable from seconds to days, and a high-efficiency boost regulator with a quiescent current of 150nA and up to 95% efficiency at higher loads. Additionally, it enables accurate battery level measurement, improving user experience and reducing unnecessary battery disposal.

Beyond power efficiency, the nPM2100 enhances system reliability. Its external watchdog can reset the host processor or restart the system, while the hard reset function allows rebooting by holding a button rather than removing the battery. The startup failure recovery feature ensures reliable operation, particularly in sealed devices where battery removal is impractical.

Packaged in a compact 1.9x1.9mm form factor, the nPM2100 requires only six external components, delivering an outstanding power management solution. As part of Nordic’s integrated wireless portfolio, it reduces system complexity, lowers the bill of materials (BoM), and saves board space. Designed to complement Nordic’s nRF52, nRF53, and nRF54 series SoCs, the nPM2100 PMIC ensures efficient power management for wearables, smart home devices, industrial sensors, and other battery-powered IoT applications.
