npm1300 dynamic charging current limit

[dani_martin]

Hi Nordic team!

Is there any way to dynamically change the charging current while the charging is ongoing? BCHGISETMSB and BCHGISETLSB can be changed only if charging is stopped, and the same for VBUSINILIM0.

I'm reviewing the npm1300 product specification v1.2...and I don't see any solution to this.

Any suggestion?

Thanks!

Charging must be stopped to change the charging parameters. VBUSINILIM0 should be updated whenever the TASKUPDATEVBUSILIM is called. Writing to the VBUSILIM0 register itself doesn't do anything until the TASKUPDATE is called
