TPS23861: Setting Single Port Output

Jerry Hsueh

Part Number: TPS23861

Hi Ti

TPS23861 can support 4 ports PSE output, but we want to specify a single port output, the other three ports can not output.

How to do it?

Thank you

Hi Jerry!

In order to specify a single port output, ground the SENX pin and leave the GATEX pin floating for each unused port. DRAINX pins can be left open or grounded, leaving open may slightly reduce power consumption. More information on unused ports can be found in Section 8.2.2 of the TPS23861 datasheet and Section 8.3 has an example of an unused port system.

The datasheet can be downloaded from this page --> http://www.ti.com/product/TPS23861/technicaldocuments

Thank you for reaching out to us today and do not hesitate to let us know if you have any more questions!
