nPM1304 Power Management IC

Highly integrated PMIC with unique system management features for small size batteries

The nPM1304 is a highly integrated multifunction Power Management IC (PMIC) that includes a battery charger, an algorithm-based fuel gauge, two ultra-efficient step-down buck regulators, two LDOs / load switches, and comprehensive system management functions into a single device. It supports battery charge current as low as 4 mA. The nPM1304 reduces the bill of materials by replacing multiple discrete components while enabling greater design flexibility through a fully I²C-compatible TWI interface. 

The nPM1304 includes an algorithm-based battery fuel gauge solution with state of charge and state of health reporting. It is highly accurate, consumes ultra-low power 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 mode.

Introduction the nPM1304

The nPM1304 complements the award-winning nPM1300 PMIC to support small size batteries

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.
