nPM1300 is a power management IC (PMIC) that 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. These functions are typically implemented as discrete components in Bluetooth Low Energy (LE) embedded designs, but 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 regula[1]tion 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 com[1]pact and advanced IoT products such as advanced wearables and portable medical applications. nPM1300 is also suitable for battery charging, fuel gauge and system management in applications based on the nRF91 Series System-in-Packages (SiPs).
