3 Description

The TPD6S300 is a single chip USB Type-C port

overvoltage and IEC ESD protection.

Since the release of the USB Type-C connector,

many products and accessories for USB Type-C have

been released which do not meet the USB Type-C

specification. One example of this is USB Type-C

Power Delivery adaptors that only place 20 V on the

mechanical sliding of the connector shorting pins, due

to the close proximity they have in this small

the CC and SBU pins. Also, due to the close

proximity of the pins in the Type-C connector, there is

a heightened concern that debris and moisture will

SBU pins.

These non-ideal equipments and mechanical events

make it necessary for the CC and SBU pins to be 20-

V tolerant, even though they only operate at 5 V or

lower. The TPD6S300 enables the CC and SBU pins

to be 20-V tolerant without interfering with normal

operation by providing overvoltage protection on the

CC and SBU pins. The device places high voltage

FETs in series on the SBU and CC lines. When a

voltage above the OVP threshold is detected on

these lines, the high voltage switches are opened up,

isolating the rest of the system from the high voltage

condition present on the connector.

Finally, most systems require IEC 61000-4-2 system

level ESD protection for their external pins. The

TPD6S300 integrates IEC 61000-4-2 ESD protection

for the CC1, CC2, SBU1, SBU2, DP, DM pins,

removing the need to place high voltage TVS diodes

externally on the connector.
