Hello,
I'd like to drive some 25mA LEDs using the Digital Output and PWM output. Can the DA14580 supply that current or I will need external driver?
I don't see this information on the Datasheet (i.e. I_OH (Output current high)).
Thank you.

Hi Casaroli, I need to check... let me come back to you on this.

Hi Casaroli,
The internal converter only can supply few mA. So you will need a MOSFET as switch and LED is supplied by VBAT3V3 for instance .

Hi, GPIOs are speced at 4.8mA in 3V buck mode. (@ Vol=0.47V)
See datasheet table 13 Digital I/O: DC characteristics
So MH_Dialog suggestion is the right way to approach the solution.

Thank you for your reply.
But I don't see this information on table 13 of the file: DA14580_DS_v3.0.pdf
我遗漏了什么东西?
Sorry, table 3, page 6...

Hi,
There is no table 3 in page 6. If you are referring to table 3 "maximum absolute ratings" on page 19, the information I am looking for is not there.
What PDF file name are you using?
HI there, its the latest datasheet on the web site (ver 3.1). Screenshot below.
