Hi Sam,

You should configure the die temperature limit according to your use case.
Please take a look at this: https://docs.nordicsemi.com/bundle/ps_npm1300/page/chapters/charger.html#ariaid-title7:~:text=interrupt%20is%20sent.-,Charger%20thermal%20regulation,-Heat%20dissipation%20from 
By default, the thermal limit for the charger is 110 Celsius.

Heat dissipation can be substantial at 800 mA, relative to the die size. E.g. if the battery is 3V, and the charger runs from 5V USB, there is 1.6W heat generation in the linear charger.

Regards,

Priyanka
