Nordic Semiconductor nPM1300 PMIC & EK
nPM1300 - Highly efficient PMIC with built-in system management features
The nPM1300 is a power management IC (PMIC) that simplifies system design by integrating essential functions required for embedded Bluetooth Low Energy designs. It features hard reset functionality for one or two buttons, accurate battery fuel gauging, system-level watchdog, power loss warning, and recovery from failed boot.
The nPM1300 is optimized for maximum efficiency and compact size, and is configurable through an I2C-compatible Two Wire Interface (TWI). This interface enables easy access and configures a range of advanced system management functions, including a two-button hard reset, battery fuel gauging, system-level watchdog, power loss warning, and recovery from failed boot. These functions are typically implemented as discrete components in Bluetooth Low Energy (LE) embedded designs, but the nPM1300 integrates them into a single, compact package, simplifying system design and reducing the number of required components.
The nPM1300 is designed to provide highly efficient power regulation for Nordic’s nRF52 and nRF53 Series System-on-Chips (SoCs), supporting wireless protocols such as Bluetooth Low Energy, LE Audio, Bluetooth mesh, Thread and Zigbee. It is ideal for compact and advanced IoT products such as advanced wearables and portable medical applications.

nPM1300 EK - Evaluation Kit for the nPM1300 PMIC (Power Management IC)
The nPM1300 Evaluation Kit allows for simple evaluation and code-free configuration of the nPM1300 Power Management IC (PMIC). By connecting to the nPM PowerUP app found in nRF Connect for Desktop, all settings of the nPM1300 can easily be configured through an intuitive GUI and exported as code to be implemented in your SoC or SiP application.
- Seamless integration and code-free configuration with the nPM PowerUP desktop app
- Male pin headers provide access to all nPM1300 PMIC connections, for easy connection to Nordic Development Kits (DK) and external test equipment
- Integrated LEDs and pushbuttons allow for evaluation of the built-in LED drivers and GPIOs of the PMIC
The kit itself offers JST battery connectors for batteries with or without internal NTC, and male pin headers for access to all nPM1300 connections. In addition, three LEDs and four pushbuttons are implemented for ease of use when evaluating the GPIO and LED diver functionality of the PMIC.
