Hi,
We have 2 projects where we are using the nPM1300.
In both cases we have peak currents.
In de documentations I thought I read some where that the current limit was 1A-2A.
Default 1.0A at reset but discharge current can be set to 1.34A.
The datasheet register description does not mention the max current limit of 1.34A only the provided driver source files by Nordic. (so far I know)
For the first project I have bypassed the nPM1300 for the motor control because of the peak current are above 2A.
For a good working fuel gauge (libnrf_fuel_gauge.a and battery model) SOC measurement the fuel gauge updates are halted for the time when the motor is running.
when motor control is shutdown ( quiescent current <0.1 uA) the fuel gauge updates start again.
This works fine for this project.
For the second project the peak currents are less intense and not so often and we hoping to not have to bypass the nPM1300.
Question:
- Wat is the max discharge current that the nPM1300 can handle and how to configer the chip?
- Are there solutions to increase the time needed before the nPM1300 discharge current feature intervenes? (this to allow the short inrush current)
