    Adrian Hunter
    It is not entirely clear (from TRMs / DMs) whether TWL4030 or TWL5030 support VAUX3 at 3V. Would someone please clarify which of these devices (and the compatible devices) support VAUX3 at 3V?

    Gandhar Dighe
    Hi, Please see some clarifications below: TPS65920 was designed with 90-ohm ULPI buffers. Therefore it requires 90 ohm ULPI traces on the board. TPS65921 was designed with 50-ohm ULPI buffers. Therefore it requires 50 ohm ULPI traces on the board. ULPI interface is not terminated...

    Antony Lin
    In TPS65921, is "pressing PWRON for 8 seconds" a switch-off event or restart event? According to my measurement, pressing PWRON for 8 sec in TPS65921 will only switch off TPS65921. But in TPS65950, it will restart TPS65850 (NRESPWRON low and high immediately.) Please help to confirm the...

    Jeff Mogensen
    Alexis, That is interesting since I am able to keep the RTC alive using a 3V coin battery connected to the TPS65921 BKBAT when the main battery has been removed from VBAT. The main battery has been removed for a over a week and time has been maintained. Perhaps VRTC is being supplied via the BKBAT...
