TUSB2036B in 2 Port mode what do I do with unused pins?

Bernt Damm

I am using this chip in the 2 Port configuraion.

Self powered compund device with PORT1 permanently connected on same pcb (no USB power switch)

What do I have to do with the unused pins:

DM3

DP3

OVRCUR3#

OVRCUR1#

Hello Bernt,

The DP and DM signals of the unused port should be tied to ground with 15K resistors like the pull-downs used on the active ports.

Unused OVRCUR# inputs should be pulled up using a 10kOhm resistor.
