Original question:

TPD6S300: what is the different between TPD6S300/TPD6S300A/ TPD8S300?

TPD8S300A: When would you want to use the 8 channel TPD8S300 vs. 6 channel TPD6S300

Part Number: TPD8S300A
Other Parts Discussed in Thread: TPD8S300, TPD6S300, TPS65982

Quick question.  Can you explain the use case where you would want to use the 8 channel TPD8S300 vs. 6 channel  TPD6S300?  What is the use case where each of the two DP and DM pins need to each have their own ESD protection (i.e. is there a use case where the DP and DM pins need to be electrically isolated on the board and not tied together, and therefore need separate protection)?

Thanks,

Matt

    Matthew,

    There are parts like TPS65982 where all for USB2.0 signal from receptacle will go to the device. The device has a mux that muxes them based on cable orientation. For more details on possible different uses of those bottom D+/D- pins you can refer to the datasheet of TPS65982( ), section 8.3.4.

    Best Regards,
