NPM2100-QEAA-R7

Battery Management Overview

The nPM2100 is a primary battery power management IC designed to extend operational life in non-rechargeable applications. It features a boost converter with up to 95% efficiency, supporting output voltages from 1.8 V to 3.3 V at currents up to 150 mA, even when input voltage drops to 0.7 V. The device includes a 50 mA LDO/load switch and offers ultra-low power modes: 35 nA transport mode and 175 nA hibernate mode with timer wake-up. It integrates a fuel gauge for accurate battery estimation and supports I2C configuration via TWI interface.

Battery Management Procurement Notes

Verify the specific suffix -QEAA-R7 against official Nordic Semiconductor documentation to confirm package type, tape-and-reel specifications, and regional compliance certifications. Ensure compatibility with target host SoCs such as nRF52, nRF53, or nRF54 series. Confirm that the ordering code matches the required pinout and thermal characteristics for your PCB layout.

Battery Management Selection Notes

Select the nPM2100 for applications requiring extended battery life from single-cell primary sources like AA/AAA or coin cells. It is suitable for designs needing flexible voltage regulation from 1.8 V to 3.3 V with minimal quiescent current. Consider this part if space constraints favor a 1.9 mm WLCSP package or if precise fuel gauge integration is required without external components.

Battery Management Part Context

The nPM2100 is part of Nordic Semiconductor's nPM family, specifically engineered for primary battery applications. It fills a market gap between basic regulators and complex multi-domain PMICs. The device complements Nordic's wireless SoC portfolio by providing optimized power management for IoT endpoints, enhancing system reliability and reducing electronic waste through improved energy utilization.

Battery Management Replacement Considerations

No direct public substitute part numbers are confirmed in the provided documentation. Designers should evaluate generic boost converters with integrated LDOs, ensuring they meet the specific 35 nA transport mode and 175 nA hibernate requirements unique to the nPM2100 architecture.
