[ LM3544 ] Unused Output Port

Hi,

Since VBUS of OUT1 will be supplied from other power path, I don't use OUT1 port as drawing below.
Can I leave this OUT1 port open without any component? or please let me know, if you have other recommendation?
Also, do you recommend to disable OUT1 power switch with EN1 pin?

Thank you for your support in advance.
Regards,
Ken

Hi Ken,

No worries as there are several forums where this part seems to fit. I moved it to what I felt was appropriate based on the "Monitors, Protectors, ..." description for this forum.

Ken,

The output pin can be left open if not being used. To disable the output, the EN1 pin should be grounded for the LM3544-H since this version is active high. I would recommend disabling the OUT1 pin by grounding EN1 if you do not need to use OUT1.

Hi Ken,

Actually, you did post to the correct forum originally but our team was not familiar with this particular device and I thought it should be moved (my fault). Thanks to Michael for eventually answering your post.

Have a nice week.
