nPM1300 - New Power Management IC for Advanced Wearables and Portable Electronics

Nordic Semiconductor has announced the upcoming release of the nPM1300, a new Power Management IC (PMIC) set to be released in mid-2023. The nPM1300 will expand the company's PMIC offerings by adding support for both charging of larger batteries and four regulated power rails. It will be optimized for efficiency and compact size, measuring 3.1 x 2.4 mm WL-CSP or 5 x 5 mm QFN. The PMIC will be digitally configurable through an I2C-compatible Two Wire Interface (TWI), providing access to various system management functions that are typically implemented as discrete components in Bluetooth Low Energy embedded designs.

Compatibility

The nPM1300 is designed for use with Nordic's nRF52 and nRF53 Series advanced wireless multiprotocol Systems-on-Chip (SoCs). It is intended for advanced IoT products, such as advanced wearables and portable medical devices. The PMIC includes features such as USB port detection, dynamic power path management, voltage and temperature monitoring, and ultra-low current hibernate mode. It also includes three LED drivers and five GPIOs that can be repurposed as control lines for time-critical functions.
