nPM1300 LED brightness control/PWM?

[timonsku]

Do the LED drivers on nPM1300 have any ability to control either current or do PWM dimming?
led_set_brightness() seems to not do anything and from the datasheet its not quite clear if there is any sort of brightness control available.
The LEDs are way too bright as is and adding limiting resistors would kind of defeat the purpose of having an LED driver on a battery powered device.

Hello,

I will look more into it and get back to you before the end of the week.

Best regards,

Hi timonsky,

Please see previous reply from Andy here - (+) npm1300 wdog and led drivers - Nordic Q&A - Nordic DevZone - Nordic DevZone (nordicsemi.com). The nPM1300 does not implement PWM control for LED, and they cannot blink autonomously, they need to be controlled by the SoC.

All the best,

Dan
