nPM1300 Power Management IC

Power Management IC (PMIC) with unique system management features

The nPM1300 PMIC simplifies system design by integrating essential functions required for embedded Bluetooth Low Energy designs into one small package, enabling longer run times and efficient battery charging with fewer components.

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 configure 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, as well as the nRF54H20 advanced wireless multiprotocol Systems-on-Chip (SoC). The PMIC is also suitable for battery charging for applications based on the nRF91 Series systems-in-package (SiPs) for cellular IoT, by using the PMIC’s unregulated output to power the SiP's internal buck regulators. The nPM1300 is also suitable for use with non-Nordic host devices.

Introducing the nPM1300 PMIC

Block diagram

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 nPM1300'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 nPM1300 Evaluation Kit along with a dedicated nPM Fuel Gauge Board.
