Connect the nPM1300 EK with nPM PowerUP

nPM1300 EK Hardware

Set up the nPM1300 Evaluation Kit (EK) to start using the nPM PowerUP app.

  1. To power the nPM1300 Power Management Integrated Circuit (PMIC), connect a USB-C cable with 1.5 A current capability to USB PMIC on J3.
  2. Insert the battery ensuring the correct polarity as shown on the EK. Depending on your battery, use one of the following alternatives:
    1. For a battery with an integrated Negative Temperature Coefficient (NTC) thermistor, use the battery connector on J2.
    2. For a battery without an integrated NTC thermistor, use the battery connector on J1. Connect a jumper between NTC (pin 2) and 10 kΩ (pin 3) on pin header P3 to use the integrated 10 kΩ resistor.
  3. Use a USB-C cable with USB 2.0 High Speed compatibility to connect from your computer to nPM CONTROLLER on J4.
    Use a ferrite bead around the USB cable to reduce electromagnetic interference.
    A green LED light (LD4) indicates a successful connection with the nPM Controller.

  4. Download and install nRF Connect for Desktop.
  5. Open nRF Connect for Desktop and install the nPM PowerUP app.
  6. Open nPM PowerUP.
  7. Click Select Device on the left-side panel.
  8. Select the nPM1300 Evaluation Kit.
  9. Set the termination voltage and current limit in the Charger panel on the DASHBOARD.
You can now see status of your battery and use the built-in battery models in nPM PowerUP.
Note: To establish a successful connection with the nPM1300 PMIC, make sure to power the PMIC first or perform a power cycle on the nPM Controller.
