nPM1300 Power Management IC

The nPM1300 PMIC 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 designed to provide highly efficient power regulation for Nordic’s nRF52, nRF53, and nRF54 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.

The nPM1300 is also suitable for battery charging, fuel gauge and system management in applications based on the nRF91 Series System-in-Packages (SiPs).

nPM Fuel Gauge Board

The nPM Fuel Gauge board is a hardware add-on to profile batteries used for fuel gauge, compatible with Nordic’s nPM1300 evaluation kit. The purpose of the board is to act as a constant current sink device during battery profiling with nPM PowerUP desktop software. The battery model generated in nPM PowerUP can be used for evaluation of fuel gauge in nPM PowerUP and exported as an include-file for use in any application using the Nordic fuel gauge algorithm.

nPM1100 Power Management IC

The nPM1100 PMIC, predecessor to the nPM1300, boasts a highly efficient dual-mode configurable buck regulator and integrated battery charger. It is designed as a complementary component to Nordic’s nRF52 Series and nRF53 Series SoCs to ensure reliable power delivery and stable operation, whilst maximizing battery life through high efficiency and low quiescent currents.

The nPM1100 can also be used as a generic PMIC device for any other suitable application. Its extremely compact form factor makes it ideal for advanced wearables, connected medical devices, and other size-constrained applications.
