The nPM1300 power management IC (PMIC) from Nordic Semiconductor integrates essential functions required for embedded Bluetooth Low Energy designs, says Rutronik, announcing that it is now available from the distributor.

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 in a single, compact package. The reduction in the number of components simplifies system design.

The PMIC is designed to provide highly efficient power control for Nordic's nRF52 and nRF53 series SoCs and ensures support for wireless networks such as Bluetooth Low Energy, Thread, Zigbee or Low Energy Audio for compact and advanced IoT applications, says Rutronik.

The nPM1300 is 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 1000mAh. The nPM1300 has four individually controllable power rails including two buck regulators with a 200mA current limit and two 100mA load switches or 50mA LDOs. Other features include five general purpose I/Os and three LED drivers.

The PMIC operates across a temperature range of -40 to 85°C.

Target applications are wearable devices, handheld entertainment devices, personal medical devices and rechargeable smart home sensors.
