nPM1304 EK Evaluation Kit

Evaluation kit for the advanced PMIC nPM1304 with battery charging and unique system management features.

The nPM1304 Evaluation Kit enables easy evaluation and programming-free configuration of the nPM1304 power management integrated circuit (PMIC). By connecting to the nPM PowerUP application in nRF Connect for Desktop, all nPM1304 settings can be easily configured via an intuitive graphical interface and exported as code for implementation in your MCU applications. 

  • Achieve seamless integration and code-free configuration through the nPM PowerUP desktop application.  
  • The male header provides all the necessary interfaces for the nPM1304 power management IC (PMIC), facilitating connection to Nordic development kits (DKs) and external test equipment.  
  • Integrated LED indicators and buttons allow for evaluation of the PMIC's built-in LED driver and general purpose input/output (GPIO) functions. 
  • Contains a 20mAh battery 

The kit itself comes with a JST battery connector for use with/without an internal NTC battery, and a male header for accessing all nPM1304 interfaces. Additionally, it integrates three LEDs and four buttons for easy evaluation of the PMIC's GPIO and LED driver functions. 

Users can directly use the pre-configured battery model in nPM PowerUP to initially evaluate the fuel gauge capabilities of the nPM1304. This fuel gauge solution relies on the battery model to achieve optimal state-of-charge accuracy. Battery modeling is a one-time operation, and the required programmable load circuitry is built into the nPM1304 evaluation kit.

nPM1304 PMIC

Highly integrated Power Management IC (PMIC) with support for small size battery products

The nPM1304 is designed to provide highly efficient power regulation for Nordic’s nRF52®, nRF53®, nRF54L and nRF54H Series. Devices using the nPM1304 and a compatible SoC also get access to the Nordic Fuel Gauge, a highly accurate, ultra-low-power way of estimating state-of-charge of rechargeable batteries.

Fuel gauging

Low power high accuracy fuel gauging tailored for embedded IoT

To accurately estimate the battery state-of-charge in percent, from 0 to 100 %, the nPM1304's fuel gauge functionality uses a model of your battery along with the battery's temperature, voltage and the current measured by the PMIC. The estimation algorithm can then be run on any Arm Cortex M4 or M33, like those found in the nRF52, nRF53 and nRF91 Series and does not require additional hardware beyond this.  

The battery model is created by doing an analysis of your specific battery, in your own lab, with the help of the nPM1304 Evaluation Kit
