Nordic Semiconductor nPM2100 PMIC Will Help Developers Enhance Non-Rechargeable Battery Project Designs

May 05 , 2025 Posted by KUKE 0

Nordic Semiconductor has introduced the nPM2100 power management integrated circuit (PMIC) for design development. Since the device's introduction in January, early customers have begun designing it into a wide range of protocell applications from personal health monitoring to wireless industrial sensors. Now, all product developers can take full advantage of the capabilities of this innovative PMIC to optimise power efficiency and system performance.

The nPM2100 is equipped with several power-saving and system management features that enable a more complete power management solution for those applications that typically use only a basic regulator. For designers of small wireless IoT applications, these features can help extend battery life or allow them to choose a smaller battery for a more compact design.

Key energy-saving features

Supports 35nA transport mode with multiple wake-up function options: enables products to be transported with batteries inserted and functions as an additional on/off button.

● Sleep mode current is less than 200nA and timed wake-ups can be set from seconds to days: extending battery life by up to 3x for products that do not have to wake up as often.

● Boost regulator delivering 150nA of current, with conversion efficiencies of up to 90.5 per cent at 10μA and up to 95 per cent at higher currents: extends the battery life of low-power products that operate at voltages higher than the battery supply.

● Battery Power Measurement: Accurately measure remaining battery power to improve the user experience and reduce premature battery disposal

Advanced system management functions

In addition, the rich features of the nPM2100 help design more reliable products that enhance the end-user experience.

● External Watchdog: Allows to reset the host processor or reboot the power of the entire system.

● Hard Reset Function: Users can long press a button to reboot without having to remove and reinsert the battery.

● Boot Failure Recovery: Allows the system to be rebooted when the host processor fails to boot, which is especially useful for closed products where batteries cannot be plugged or unplugged.

The nPM2100 integrates these features in a small 1.9x1.9mm package, requiring only six external components to deliver an outstanding power management solution to the market.

Seamless integration of Nordic's complete wireless solutions

Nordic's nPM family of PMICs are highly integrated solutions that reduce system complexity, bill of materials (BoM) and footprint. By integrating the nPM2100, developers can optimise battery performance and system efficiency from battery to antenna. Designed to complement the market-leading nRF52, nRF53 and nRF54 family of SoCs, the nPM2100 PMIC, as part of Nordic's complete low-power wireless solution, ensures efficient power management for wearables, smart home devices, industrial transmitters and other primary battery-powered IoT applications.

Delivery and Packaging

The nPM2100 is sampling now in the WLCSP package and will begin sampling in the next few weeks in the QFN package. nPM2100 will enter volume production in June and September 2025 for the WLCSP and QFN packages, respectively.
