Nordic Semiconductor has unveiled a power management IC (PMIC) designed to prolong operating time per battery for consumer devices, asset tracking, remote controls and healthcare wearables.
Called the nPM2100, the PMIC managed the power supply for low-power system-on-chips (SoCs) or microcontrollers (MCUs) such as Nordic’s nRF52, nRF53 and nRF54 for wireless multiprotocol products. The PMIC optimizes efficiency, size and configurations through an I2C-compatible two wire interface (TWI).
The interface allows access to configure a range of functions like ship mode and accurate battery fuel gauging. Other features include:
- Two GPIOs
- Efficient boost regulator
- Other energy-saving components to extend operating time
Why it matters
According to the European Union’s CORDIS project, up to 78 million batteries will be discarded daily in 2025 making battery life expanding technologies critically important as IoT devices are growing exponentially.
The project said that the need for energy harvesting technology is critical to improve IoT device battery lifespans as well as technologies that will reduce overall energy consumption in these devices.
