Effective immediately, the new nPM1300 Power Management IC (PMIC) from Nordic Semiconductor expands Rutronik’s portfolio. nPM1300 already integrates essential functions required for embedded Bluetooth Low Energy designs. It provides hard reset functions for one or two buttons, accurate battery indication, a system-level watchdog, power failure warning, and recovery from a failed startup – all in a single, compact package. This reduces the number of components required and simplifies system design. Designed to provide highly efficient power control for Nordic’s nRF52 and nRF53 series system-on-chips (SoCs), the nPM1300 ensures support for wireless networks such as Bluetooth LE, Thread, Zigbee or LE Audio. This makes the PMIC ideal for compact and advanced IoT applications. It is available at www.rutronik24.com.
In addition, the nPM1300 is highly power efficient and comes with accurate measurement functions for monitoring charge level and estimating battery life. It is suitable for use with USB-C compatible chargers for lithium-ion, lithium-polymer, and lithium iron phosphate batteries up to 1000 mAh. The nPM1300 has four individually controllable power rails including two high-performance buck regulators with a 200 mA current limit and two 100 mA load switches or 50 mA LDOs. The Power Management IC operates reliably at operating temperatures from -40° C to +85° C.
