The nPM1300 power management IC (PMIC) from Nordic Semiconductor is now available at Rutronik. The IC integrates essential functions required for embedded Bluetooth Low Energy designs with 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 device. The level of integration and compact package reduces the number of components required and simplifies system design, said Rutronik.
It is designed to provide efficient power control for Nordic’s nRF52 and nRF53 series SoCs and ensures support for wireless networks such as Bluetooth LE, Thread, Zigbee or Low Energy Audio.
The nPM1300 is also power efficient and includes accurate measurement functions for monitoring charge level and estimating battery life. It can be used 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 high performance buck regulators with a 200mA current limit and two 100mA load switches or 50mA LDOs. The PMIC has an operating temperature range of -40 degrees C to +85 degrees C.
The battery charger complies with JEITA and has a termination range of 3.5 to 4.45V and charge current from 32 to 800mA. The input regulator has an input range of 4.0 to 5.5V and output from 4.0 to 5.5V unregulated. USB current limit is 1500mA and the design includes overvoltage protection at 22V transient.
Other features include an input regulator with USB support, an 800mA charger, ship- and hibernate modes and five general purpose I/Os and three LED drivers.
The nPM1300 PMIC can be used in a choice of applications for wearable devices, handheld entertainment devices, personal health and medical devices and rechargeable smart home sensors.
