The nPM2100 PMIC enables longer run-time on every battery by implementing toolbox of power saving capabilities for primary cell batteries.
It features one boost converter that can provide voltages of 1.8 to 3.3 V output, from input voltages of 0.7 to 3.4 V. Examples of supported batteries are one or two AA/AAA/LRxx batteries (in series), or one 3V LiMnO2 cell. Single- or dual-cell silver oxide and zinc-air coin-cell batteries are also supported, or any other battery that operates within the PMICs input voltage range.
The 150 nA iQ internal boost regulator places itself among the most efficient boost regulators on the market today. A 35 nA ship mode allows the device to be shipped with batteries inserted without draining the battery and eliminates the plastic pull-tab method of protecting batteries during shipping and storage. Hibernate mode includes timed wakeups for applications that spend most of their time in deep sleep, lowering sleep current to 175 nA extending battery lifetimes by up to 3x.
Designed to provide highly efficient power regulation for any primary-cell application, the nPM2100 comes with exceptional software support for Nordic’s nRF52, nRF53, and nRF54 Series of wireless multiprotocol Systems-on-Chip (SoC) in the nRF Connect SDK. The nPM2100 is also suitable for use with non-Nordic host devices.
The nPM2100 features precise algorithm-based fuel gauging. Standard voltage-based estimation is often inaccurate, leading to premature replacements or unexpected depletion. Instead, the nPM2100 uses a voltage and temperature-based fuel gauge on the host microprocessor for more accurate readings, ensuring full battery utilization with minimal additional load.
The nPM2100 comes in a compact 1.9 x 1.9 mm WLCSP and a versatile 4 x 4 mm QFN16 package.
