Power Management ICs – Designed to reduce power consumption

Power Management IC (PMIC) with unique system management features – nPM1300  

Nordic announced the release of a third power management IC (PMIC) in mid-2023 to expand its PMIC portfolio. The nPM1300 PMIC simplifies system design by integrating essential functions required for embedded Bluetooth^® Low Energy designs into one small package, enabling longer battery life and efficient battery charging with fewer components. Optimized for maximum efficiency and compact design (3.1 x 2.4mm WL-CSP or 5 x 5mm QFN), the nPM1300 is digitally configurable via an I2C-compatible Two Wire Interface (TWI). This interface allows easy access and configuration of a number of advanced system management functions, including a hardware reset functionality, battery fuel gauge, system-level watchdog, power loss warning, and failed boot recovery. These functions are typically implemented as discrete components in Bluetooth^® LE embedded designs. The nPM1300 integrates them into a single, compact package, simplifying system design and reducing the number of required components. The nPM1300 is designed to provide highly efficient power regulation for Nordic's nRF52 and nRF53 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.
