nPM1304 EK Evaluation Kit

Evaluation kit for the nPM1304, a highly integrated Power Management IC (PMIC) with battery charging and advanced system management features

The nPM1304 Evaluation Kit (EK) enables fast evaluation and code‑free configuration of the nPM1304 PMIC using the nPM PowerUP desktop application in nRF Connect for Desktop. Through an intuitive graphical interface, all PMIC settings can be configured and exported as code for direct integration into the host MCU application. 

The EK provides male pin headers for access to all nPM1304 connections, allowing easy connection to Nordic Development Kits (DKs) and external test equipment. Integrated LEDs and pushbuttons enable evaluation of the PMIC’s built‑in LED drivers and GPIO functionality, while JST battery connectors support batteries with or without an internal NTC. A 20 mAh battery is included for immediate evaluation. 

For fuel‑gauge evaluation, users can start with pre‑profiled battery models included in nPM PowerUP. For best state of charge and state of health accuracy, battery profiling and model generation is a one‑time process, and the nPM1304 EK includes the programmable load circuitry required to perform this profiling directly—no external fuel‑gauge board is needed.

Differentiated algorithm-based battery fuel gauge solution including battery health

Accurate fuel gauging is essential for any battery‑powered device, giving users clear and reliable insight into how much energy is left and helping avoid unexpected shutdowns.

Nordic’s fuel gauging provides accurate state of charge information for all supported battery types. Battery state of health is also supported for rechargeable batteries - tracking actual capacity and aging over time to understand how the battery performs throughout its lifetime. This deeper insight helps devices stay reliable for longer and makes rechargeable battery replacement more predictable.

By combining high accuracy with ultra‑low power operation - including zero power consumption in sleep - and low system cost, the Nordic algorithm-based fuel gauge solution delivers accurate battery information without extra components, licensing fees, or impact on battery life.
