Part Number: TPD6S300

Please let me know about overvoltage function for CC1, CC2, SBU1, and SBU2 Pin for TPD6S300.

When any one line (ex. CC1) detect overvoltage, which SW off function only CC1 line or four all line?

Best regards,

Hi Satoshi,

When an OV occurs on one of the channels (let's say CC1), then that channel's switch will open in about 70ns (NOT all 4 channels, only the channel with an OV event). The voltage will be clamped during the 70ns.

The OV threshold for CCx and SBUx are in the Electrical Characteristics table in the datasheet (look below). I hope this helps, and If this answers your question, PLEASE select This resolved my issue
