            nPM1300 Power Management ICs
                    Nordic Semiconductor’s nPM1300 PMICs provide battery charging, accurate fuel gauging, and advanced system management features
    

Nordic Semiconductor’s nPM1300 power management ICs (PMIC) simplify system designs by integrating essential functions required for embedded Bluetooth® low energy (BLE) designs. They feature a hard reset function 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 BLE 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 regulation for Nordic’s nRF52 and nRF53 series systems on chips (SoCs), supporting wireless protocols such as BLE, LE audio, Bluetooth mesh, Thread, and Zigbee®. They are ideal for compact and advanced IoT products such as advanced wearables and portable medical applications.
