Nordic Semiconductor Declares Multi-Operate Energy Administration IC

The most recent addition to Nordic’s PMIC portfolio, the nPM1300 PMIC simplifies system design
by integrating important features required for Bluetooth Low Power embedded designs,
whereas supporting longer run occasions and environment friendly battery charging.

Nordic Semiconductor as we speak publicizes its plan to launch a 3rd Energy Administration IC (PMIC) in mid-2023 to broaden its PMIC portfolio. The nPM1300 expands the corporate’s
PMIC providing by including help for each charging of bigger batteries and 4 regulated energy rails. The nPM1300 can be optimized for effectivity and compact measurement (3.1 x 2.4 mm WL-CSP or 5 x 5 mm QFN) and is digitally configurable by way of an I 2 C-compatible Two Wire Interface (TWI). The digital interface supplies entry to a number of system administration features which might be often carried out as discrete features in Bluetooth Low Power (LE) embedded designs – resembling onerous reset, battery gasoline gauge, system-level watchdog, energy loss warning, and restoration from failed boot.

“Nordic entered the PMIC market as a result of current energy administration options weren’t optimized for compact, ultra-low energy IoT purposes. Out there PMICs go away it as much as the designer to implement important performance utilizing discrete elements – features that naturally belong inside a PMIC and will be carried out at virtually no price,” says Geir Kjosavik, Product Director – PMIC, Nordic Semiconductor. “So, we did simply that. Nordic’s clients can be delighted to have entry to on-chip features that improve product security and supply further methods of conserving battery vitality.”

Designed for superior IoT

The nPM1300 is designed to offer extremely environment friendly energy regulation for Nordic’s nRF52 and nRF53 Collection superior wi-fi multiprotocol Programs-on-Chip (SoCs). The PMIC’s 4 regulated energy rails and battery charger make it superb for compact and superior IoT merchandise based mostly on, for instance, an nRF5340 SoC host and a number of peripheral features resembling sensors. Examples embody superior wearables and moveable medical purposes.

The nPM1300 PMIC operates from an exterior energy provide of 4.0 to five.5 V and may function from a battery voltage right down to 2.4 V. Two energy rails are regulated by separate DC/DC buck converters which might be configurable between 1.0 and three.3 V and as much as 200 mA most present. The opposite two energy rails function as load switches—switching currents of as much as 100 mA from exterior sources—however may carry out as Low Drop Out (LDO) voltage converters when powered straight by the nPM1300. When working as LDOs, these energy rail outputs are configurable between 1.0 and three.3 V with a most output present of fifty mA. The unregulated enter voltage can be obtainable as an output from the nPM1300.

The nPM1300 costs single-cell Li-ion, Li-Pol, and LiFePO4 batteries with a linear charging module that helps as much as 800 mA cost present. The termination voltage is programmable from 3.5 to 4.45 V. The battery charger options computerized thermal regulation with programmable most chip temperature throughout charging to allow easy thermal administration that may be tailored to any system requirement.

USB port detection and extra

The nPM1300 brings different new superior options to Nordic’s PMIC vary together with: USB port detection with computerized present limits of 100 mA or 500 mA by way of customary USB or as much as 1500 mA by way of USB-C PD (Energy Supply); dynamic energy path administration which routinely switches to battery energy if a mains energy connection is eliminated; voltage, present and temperature monitoring for correct gasoline gauging; and ultra-low present hibernate mode with a programmable wake-up timer along with the opposite system administration options already talked about. The PMIC additionally options three LED drivers and 5 GPIOs that may be re-purposed to direct management traces to time-critical management features as an alternative choice to serial instructions.

The nPM1300 is obtainable for restricted sampling now, and can be obtainable to order from Nordic’s distributors mid-2023.
