TPS65982 for SuperSpeed+

Other Parts Discussed in Thread: TPS65982, HD3SS460

Hi

I have some question from our customer. Could you give us any advice about the following question?

1. Does TPS65982 has a multiplexer for Super Speed +?
2. Does TPS65982 support display mode(HDMI)?
3. Does TPS65982 has a switch which selects the CC to power line or signal line?
4. How much is the current consumption of TPS65892 at each mode(DRP, DFP, UFP)?
Regards,
Koji Hamamoto

    1. No, the TPS65982 provides Automatic control of the HD3SS460 and other SuperSpeed muxes by using GPIOs triggered by USB-C & PD Events

    2. HDMI is not a defined Alternate Mode for the USB-PD spec. DisplayPort (SVID = 0xFF01) is the only USB-IF sanctioned Video Alternate Mode. Most Docks/Monitors have another DPort to HDMI (or VGA) converter behind the SuperSpeed Mux

    3. Yes, the TPS65982 does this automatically. Whichever CCX pin has an Rd pull down (typ. 5.1kOhm) is CC, and the other must have an Ra Pull-Down (typ. 1kOhm) for VCONN to be supplied from PP_CABLE.

    4. Power measurements for the TPS65982 are FW dependent and are classified into 3 categories: Active, Idle, & Sleep. Please refer to the TPS65982 datasheet for approximate current consumption in each sleep state. DRP in Idle/Sleep mode is still considerably higher than the measured current, which is measured as a DFP or UFP (Rp & Rd not toggling, which causes a wake event). Different FW will produce different power consumption by the TPS65982, and these measurements are only approximate based on a generic fully functional FW image.
