nPM1300 Power Management IC

Highly integrated PMIC with unique system management features.

The nPM1300 is a highly integrated multifunction Power Management IC (PMIC) that includes battery charger, an algorithm-based fuel gauge, two ultra-efficient buck regulators, two LDOs / load switches, and comprehensive system management functions into a single device. The nPM1300 reduces both board space and bill of materials while replacing multiple discrete components while enabling greater design flexibility through a fully I²C-compatible TWI interface. 

The nPM1300 includes an algorithm-based battery fuel gauge solution with state of charge and state of health reporting. It comes with coulomb counter accuracy, ultra-low power operation and does not require any extra components. A rich set of system management features including a hardware watchdog, power loss warning, hard reset supervisory circuit, failed boot recovery, ship and hibernate modes.

Introduction the nPM1300

Introducing the nPM1300 PMIC

DevAcademy

Designing Low-Power Bluetooth LE Products, including a dedicated PMIC lesson

Master low-power design for Bluetooth LE products with nRF54 Series SoCs and learn how to design with PMICs, including hands-on PMIC integration with the nPM2100.

In the PMIC lesson you will explore:

  • PMIC overview
  • System management features with Nordic PMICs
  • System efficiency considerations
  • PMIC hardware integration
  • PMIC software integration
  • Getting started with Nordic PMICs
  • Powering nRF54L devices from a single AA/AAA battery using the nPM2100 PMIC

                                                             

                                                                                     
 

To get the most out of this course, we recommend using an nRF54L15 DK, a Power Profiler Kit II (PPK2), and an nPM2100 EK. The course also supports the nRF54LM20 DK, nRF54LS05 DK, and nRF54LV10 DK.
