nPM1100 电源管理IC

引脚可配置、小型化封装电源管理芯片(PMIC)

nPM1100 是一款电源管理芯片(PMIC),集成电池充电器与双模式可配置降压稳压器。该器件可简化电源设计,兼具高转换效率与低静态电流,在空间受限的可穿戴、医疗及物联网设备中最大限度延长电池续航。芯片支持全引脚配置,无需软件即可完成配置与控制。

包含全部无源器件在内,整套方案占用面积最低仅 23 平方毫米,依托 nPM1100 即可实现小型化电池供电产品设计,替代以往需要多款分立元器件的方案;若为优化转换效率进行设计,所需 PCB 面积会略有增加。

Evaluation kits

nPM1100 EK

The nPM1100 Evaluation Kit (EK) is a tool for evaluating the nPM1100 PMIC and evaluate its features for your application. The kit features switches for all selectable settings, buttons to enter and exit ship mode and connectors for batteries, USB and headers for all pins on the PMIC.

Software & tools

Nordic’s PMIC software and tools are designed to simplify power management development across Nordic and non‑Nordic MCUs. With ready‑to‑use drivers for Zephyr and bare-metal environments, a production‑proven fuel‑gauge algorithm, and powerful evaluation tools like nPM PowerUP, developers can evaluate, configure, and integrate PMICs quickly — moving fast from first prototype to final product.

The Software & Tools landing page brings together all software, documentation, downloads, and development resources needed to support PMIC‑based designs.
