Application example for nPM1100 with nRF5x from Nordic-Semi
The following application example uses NPM1100 and an nRF5x wireless System on Chip (SoC).
Any nRF52 or nRF5340 series device with USB can be configured in the same way as with this application example.
The example application is for a design with the following configuration and features:
• NPM1100 BUCK regulator supplies the nRF5x device
• USB current limit negotiation
• Charging status monitoring using SoC GPIOs (General Purpose Input/Outputs)
• ICHG (Charge current limit) and VTERM (Termination Voltage) configuration
• NTC (Negative Temperature Coefficient) thermistor in the battery pack
• Ship mode
• Battery monitoring circuit and low battery indication LED
