100uA Current Source for

Hi,

The SLG46110 datasheet and the Designer both mention a "100uA current source option" for ACMP1 but there are no further details.

Does this current source pull up on Pin 4 and/or Pin 6? Are there accuracy and pin voltage range specifications?

Thanks!

Device:
DA14580

Hi Seth,

Hi Seth,

yes you are right. The current source pulls up IN+ of comparator to internal Vref 1.8V or to the VDD, depends on the chip. See alsohttps://support.dialog-semiconductor.com/forums/post/greenpak-and-greenf...

Thanks,
