The nPM1300 is designed to provide highly efficient power regulation for Nordic''s nRF52 and nRF53 Series, as well as the nRF54L and nRF54H Series wireless multiprotocol Systems-on-Chip (SoC). The PMIC is also suitable for battery charging for applications based on the nRF91 Series systems-in-package (SiPs) for cellular IoT, by using the PMIC
In this field test we have captured several data parameters, captured the power consumption of the device, and used the Nordic specific connection evaluation feature to evaluate the network link before sending Uplink (UL) data using UDP (User Datagram Protocol). This was captured both using LTE-M and NB-IoT technologies with an interval of 1 km away from the
The nRF51 is in debug mode. Solution: Power reset the chip in order to enter normal mode. If you are using nRF51-DK, disconnect USB and power the nRF51-DK board from a battery to measure the lowest current consumption. USB adds around 1uA-2uA. The nRF51 remains in debug mode after power reset on custom board.
The nPM1100 is a dedicated power management IC (PMIC) with a highly efficient dual-mode configurable buck regulator and integrated battery charger. It is designed as a complementary component to Nordic''s nRF52® Series and nRF53® Series System-on-Chips (SoCs) to ensure reliable power delivery and stable operation, whilst maximizing battery
I measured the power consumption of the development kit with PPK2 and I observed interesting behaviour. At the beggining it took ~8 seconds to initialize and connect to border router during which the power consumption was 4.6 mA. After that, the power consumption is 80 μA. In the plot I can see clearly communication every 10 seconds (several 18 mA peaks)
Low battery behavior. Nordic System-on-Chip (SoC) designs are aimed at ease of use and ultra-low power consumption. A power-optimized development ecosystem typically consists of the following developer tools: nRF Connect SDK. Development kits. Online Power Profiler (OPP) Power Profiler Kit II (PPK2)
To achieve the lowest power consumption possible, the PMU optimizes the system by evaluating power and clock requests, automatically starting and stopping clock sources, and choosing regulator operation modes. There are some configuration options that enable you to implement extra power management policies.
The power options are the following: • USB connector J2 for the interface MCU (5 V) • USB connector J3 for the nRF5340 SoC (5 V) • Li-Poly battery connectors J6 or P27 (2.5 V to 5.0 V) • VIN 3–5V pin on P20 (3.0 V to 5.0 V) •...

I used to do 14.6 which is 3.65x4 but one cell wandered and it would cut my power on and off repeatedly. Since then I want the whole battery to cooperate and not have a cell slightly off messing with me. Reactions: Sheepy and Yobbo. Y. Yobbo New Member. Joined Sep 28, 2020 Messages 6.

PSM and eDRX settings can be configured throught the prj nf file in the project folder. Below is a current plot showing the application without any modifications. The area between the cursors is when the modem has entered PSM. Check if you have actually entered PSM. Sometimes the network will not give you the same parameters as requested. If
When SW10 is ON, the chip is always powered from external supply. So setting it on VDD should give correct measurements. Currently I have connected nRF52840 DK to the USB. Li-Po battery also in place. SW9 selected as VDD. SW10 is OFF.
The easiest way of taking advantage of these drivers is to add the nPM1300 EK shield to your application. The label for the nPM1300’s BUCK1 is npm1300_ek_buck1, and the function for setting the voltage is “regulator_set_voltage”, with the buck and the min and max allowed voltages given in microvolts as arguments.
Introducing nPM PowerUP: With nPM PowerUP, all the functionality of the nPM1300 PMIC is configurable through a user-friendly GUI. Selecting the output voltage is as easy as setting the slider to the desired voltage or punching in the number if you prefer. Then, click the “export configuration” button in the top left corner.
