The nPM1300 EK has three LEDs for visualizing the status of the nPM1300 Power Management Integrated Circuit (PMIC).
Figure 1. LED indicators for nPM1300 PMIC status
The PCB overlay shows the default states for the LEDs. The LEDs can be configured in software for custom use.
Jumpers on pin header P17 connects the LEDs on the EK to the PMIC LED pins. During current measurements, or if using external LEDs, the LEDs can be disconnected from the PMIC by removing the jumpers.
| PMIC pin | Part | Function | Color | Connecting jumper pins |
|---|---|---|---|---|
| LED0 | LD1 | ERR (error) | Red | P17 pin 1 to pin 2 |
| LED1 | LD2 | CHG (charging) | Green | P17 pin 3 to pin 4 |
| LED2 | LD3 | HOST (host activity) | Amber | P17 pin 5 to pin 6 |
