Nordic Semiconductor PMIC targeted at complex IoT applications

Article By : Nordic Semiconductor

The nPM6001 is a dedicated PMIC with six independently-controlled power rails designed to supervise and supply the power requirements of complex IoT hardware.

Nordic Semiconductor has added one more power management IC (PMIC) to its product portfolio. Designed to supervise and supply the power requirements of complex IoT hardware incorporating multiple power domains that each require separate voltage regulation, the nPM6001 is a dedicated PMIC with six independently-controlled power rails. It can also be used to independently power down each power domain to conserve energy and extend the battery life of the IoT device.

The nPM6001 can be used to power Nordic’s nRF7002 ultra-low power, dual-band Wi-Fi 6 companion IC, and the nRF52 and nRF53 Series ultra-low power wireless Systems-on-Chip (SoCs) in systems with highly partitioned power architectures. Nordic’s nPM1100 PMIC can be used as a complementary device to the nPM6001 to add battery charging to nPM6001-powered applications. Alternatively, the nPM6001 can be used to increase the number of regulated power rails in nPM1100-powered applications from one to seven.

The nPM6001 features four highly-efficient step-down (buck) regulators that can deliver 500, 200, 150 and 150mA respectively at selectable voltage outputs ranging from 0.7 to 3.3, 2.1, 2.7, or 3V. In addition, two low dropout (LDO) regulators can supply up to 15mA fixed at 1.8V, and up to 30mA selectable between 1.8 and 3.3V respectively.

How Emerging Connectivity Standards are Supporting New Applications and Services

Emerging long-range technology standards such as LTE-M and NB-IOT are both delivering new features and applications to developers. Together with the new standards such as 5G Non-Terrestrial Networks (NTN) and DECT NR+, they will bring even more possibilities to the industry. Combining these with existing short-range standards such as Bluetooth Low Energy and Wi-Fi, along with a flexible, truly ultra-low power platform, will allow for the development of more sustainable and efficient “Things” for the IoT world.

Wendell Boyd, Director of Sales, ASEAN and ANZ, at Nordic Semiconductor will be discussing these, and more, at the upcoming Electronics Asia Conference (EAC) 2022.

The PMIC also incorporates a watchdog timer (WDT) that can be set to time-out between 4s and 776.7 days in 4s increments. The WDT resets if not triggered before it times out. The WDT is also used to implement hibernate mode; in this mode, the whole PMIC system—except for a 2kHz oscillator and a timer—is powered down. Power consumption in hibernate mode is 300nA typical.

Supporting advanced IoT hardware

“The nPM1100 PMIC has proven a popular compact solution for charging batteries and power delivery, but more complex IoT applications require more than the single power rail it supports,” says Geir Kjosavik, Product Director – PMIC with Nordic Semiconductor. “With six independently controlled power rails, the nPM6001 has the scope to handle the most advanced IoT hardware our customers are designing.”

The nPM6001 is delivered in a 2.2-by-3.6mm chip scale package. Interested parties are advised to contact their local Nordic sales representative for more information.

Nordic pioneered ultra-low power wireless technology and constantly strives to further reduce the power consumption of its technology. The result is extended battery lifetime, reducing the need to manufacture and dispose of batteries, and support for designers to develop sustainable energy resources to power their applications. Nordic’s PMICs are engineered to efficiently manage power resources to complement Nordic’s ultra-low power consumption strategy.
