Nordic Semiconductor nPM1300 - Measure VBUS Current

Measure current
• PPK2 VOUT to nPM1300 EK VBAT on P1 (pin 3)
2. Make sure a jumper is connected between VBATIN and VBAT on P1 (pins 1 and 2).
3. Connect the load (nRF5340 DK in this example) to VOUT1 (pin 1 or 2) and GND (pin 3 or 4) on
nPM1300 EK P4.
4. Connect the PPK2 to a computer using a USB cable.
5. Start the Power Profiler app.
6. Select your PPK2.
7. Select Source Meter as the mode.
8. Set the supply voltage to value between 2.3 V to 4.45 V.
9. Toggle Enable power output to power the nPM1300 EK.
10.Click Start.
5.3.2 Measure VBUS current
The Power Profiler Kit II (PPK2) is operated in Source Meter mode for this configuration.
1. Connect the PPK2 to the nPM1300 EK with the 4-pin measurement cable using the following pins:
• PPK2 GND to nPM1300 EK GND on P2 (pin 4)
• PPK2 VOUT to nPM1300 EK VBUS on P2 (pin 1)
2. Connect the load (nRF5340 DK in this example) to VOUT1 (pin 1 or 2) and GND (pin 3 or 4) on
nPM1300 EK P4.
