Power Management

Our Power Management ICs (PMICs) are designed with low power consumption and compatibility with our products first in mind. Building on years of experience of integrating power management into our SoCs.

Built-in power management on SoCs

Ever since the release of the first SoC (System-on-Chip) from Nordic Semiconductor, our focus have been on delivering wireless connectivity with the lowest possible power consumption. This has resulted in us becoming a market leader in the Bluetooth Low Energy space, but we've also gained a lot of knowledge about how to power our devices efficiently.

As an example of this our flagship low power short range wireless SoC, the nRF5340 contains internal regulators to enable direct battery operation. It also has enough overhead to allow powering other components like a sensor with about 10 mA of current. But internal power management in SoCs also comes with some limitations, the smaller manufacturing process that the nRF5340 is built on is not optimal for power management at higher load capacities.

Dedicated Power Management ICs

By selecting a larger process for a dedicated Power Management IC (PMIC) you achieve better performance and efficiency, and this is why a lot of applications will need a dedicated PMIC for power delivery. PMICs also may offer additional features like charging circuits and battery management, drivers for LED indicators, overvoltage protections and USB detection capabilities. With our focus on low power wireless connectivity, we have gained experience in not only how to make efficient SoCs, but also how to power them efficiently. This is a knowledge we want to utilize to the fullest.   

The first ever standalone Power Management IC to emerge from the Nordic Semiconductor lineup of products, the nPM1100, built on the experience of integrating power management into our SoCs. Truly wireless devices needs batteries, and batteries needs charging. That's why it feels natural for us to offer a complete solution of devices to enable you to make completely wireless products, wirelessly enabled by a Nordic SoC - powered by a Nordic PMIC.

Products

for Power Management

nPM1100 PMIC

Ultra-small form-factor Power Management IC (PMIC) for charging batteries and power delivery.

The nPM1100 is a dedicated power management IC (PMIC) with dual-mode configurable buck regulator and integrated battery charger. It is designed as a complementary component to Nordic’s nRF52® Series and nRF53® Series System-on-Chips (SoCs) to ensure reliable power delivery and stable operation, whilst maximizing battery life through high efficiency and low quiescent currents. It 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. PCB area usage can be as low as 23 mm2.

Tools

for Power Management

nPM1100 EK

The nPM1100 Evaluation Kit (EK) is a tool for evaluating the nPM1100 PMIC and evaluate its features for your application. The kit features switches for all selectable settings, buttons to enter and exit ship mode and connectors for batteries, USB and headers for all pins on the PMIC.

Power Profiler Kit II

The Power Profiler Kit II is an easy-to-use tool for measuring and optimizing power consumption for embedded solutions.
