二，nPM1300 EK 概述

用户可通过nPM1300评估套件对nPM1300电源管理IC（PMIC）进行简便的评测和配置。通过连接到nRF Connect for Desktop中的nPM PowerUP应用程序，可以运用直观的图像用户界面（GUI）轻松配置nPM1300的全部设置，并将其作为代码导出，在MCU应用中运行。

  • 通过nPM PowerUP桌面应用程序实现无缝集成和配置
  • 通过公头引脚访问所有的nPM1300 PMIC连接，轻易连接Nordic开发套件(DK)和外部测试设备
  • 使用集成的LED和按钮，可对PMIC的内置LED驱动器和GPIO进行评测

nPM1300评估套件自带JST电池连接器，用于带有或不带内部NTC的电池，以及用于访问全部nPM1300连接的公头引脚。此外，该套件还带有3个LED和4个按钮，简化了PMIC的GPIO和LED驱动功能的评估工作。

要初步评估nPM1300内的电量测量能力，用户可以使用nPM PowerUP中已经包含的预配置电池模型之一。电量计量表解决方案配合电池模型，可准确测量设备充电状态。分析电池并生成电池模型是一次性的工作，你需要一些额外的硬件。

nPM1300旨在为Nordic的nRF52®和nRF53®系列，以及nRF54H20先进无线多协议系统级芯片(SoC)提供高效的电源调节功能。这款PMIC还适用于基于蜂窝物联网nRF91系列系统级封装(SiP)的应用的电池充电，方法是使用PMIC的非稳压输出为SiP的内部降压稳压器供电。

三，Set up the nPM1300 Evaluation Kit (EK) to start using the nPM PowerUP app.
  • To power the nPM1300 Power Management Integrated Circuit (PMIC), connect a USB-C cable with 1.5 A current capability to USB PMIC on J3.
  • Insert the battery ensuring the correct polarity as shown on the EK. Depending on your battery, use one of the following alternatives:
    • For a battery with an integrated Negative Temperature Coefficient (NTC) thermistor, use the battery connector on J2.
    • For a battery without an integrated NTC thermistor, use the battery connector on J1. Connect a jumper between NTC (pin 2) and 10 kΩ (pin 3) on pin header P3 to use the integrated 10 kΩ resistor.
  • Download and install nRF Connect for Desktop.
  • Open nRF Connect for Desktop and install the nPM PowerUP app.
  • Open nPM PowerUP.
  • Click Select Device on the left-side panel.
  • Select the nPM1300 Evaluation Kit.
  • Set the termination voltage and current limit in the Charger panel on the DASHBOARD.

    You can now see status of your battery and use the built-in battery models in nPM PowerUP.
  • Use a USB-C cable with USB 2.0 High Speed compatibility to connect from your computer to nPM CONTROLLER on J4.
    Use a ferrite bead around the USB cable to reduce electromagnetic interference.
    A green LED light (LD4) indicates a successful connection with the nPM Controller.
