nPM1304 EK Evaluation Kit

Evaluation Kit for the nPM1304, a highly sophisticated Power Management IC (PMIC) with battery charging and unique system management features

The nPM1304 Evaluation Kit allows for simple evaluation and code-free configuration of the nPM1304 Power Management IC (PMIC). By connecting to the nPM PowerUP app found in nRF Connect for Desktop, all settings of the nPM1304 can easily be configured through an intuitive GUI and exported as code to be implemented in your MCUs application. 

  • Seamless integration and code-free configuration with the nPM PowerUP desktop app 
  • Male pin headers provide access to all nPM1304 PMIC connections, for easy connection to Nordic Development Kits (DK) and external test equipment  
  • Integrated LEDs and push buttons allow for evaluation of the built-in LED drivers and GPIOs of the PMIC 
  • 20 mAh battery included

The kit itself offers JST battery connectors for batteries with or without internal NTC, and male pin headers for access to all nPM1304 connections. In addition, three LEDs and four pushbuttons are implemented for ease of use when evaluating the GPIO and LED driver functionality of the PMIC. 

For initial evaluation of the fuel gauging capabilities within the nPM1304, users may use one of the pre-profiled battery models already included in nPM PowerUP. The fuel gauge solution relies on a battery model for best state-of-charge accuracy. Profiling your battery and generating a battery model is a one-time effort and the nPM1304 EK contains the programmable load circuitry required for this.

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
