The nPM2100 Power Management IC (PMIC) is designed for primary (non-rechargeable) batteries in an extremely compact form factor. It features an ultra-efficient boost regulator and a wide range of energy-saving features, all of which extend the operating time for non-rechargeable battery applications. nPM2100 provides power regulation for low power microcontroller units (MCU) and System-on-Chip (SoC) devices, like the nRF52, nRF53, and nRF54L Series advanced wireless multiprotocol SoCs from Nordic Semiconductor.

It features one boost regulator that supplies 1.8 V to 3.3 V output, from input voltages of 0.7 V to 3.4 V. Supported batteries include any battery that operates within the input voltage range of nPM2100.

The 150 nA IQ internal boost regulator is among the most efficient boost regulators on the market. A 35 nA Ship mode allows the device to be shipped with batteries inserted without draining the battery. Timed wakeup is available in Hibernate mode for applications that spend most of their time in deep sleep, lowering sleep current to 175 nA and extending battery lifetime by almost triple.

Designed to provide highly efficient power regulation for any primary-cell application, nPM2100 comes with exceptional software support found in the nRF Connect SDK. nPM2100 is also suitable for use with other host devices.

nPM2100 supports precise algorithm-based fuel gauging. Standard voltage-based estimations are often inaccurate, leading to replacing batteries that are still charged, or unexpected shutdown. Instead, nPM2100 uses a voltage and temperature-based fuel gauge running on the host microprocessor for more accurate readings, ensuring full battery utilization with minimal additional load.
