3 Description

The TPD4S201-Q1 is a single-chip USB Type-C port

protection device that provides 28V short-to-VBUS

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 that do not meet the USB Type-C

specification. Another concern for USB Type-C is that

mechanical twisting and sliding of the connector could

short pins due to the close proximity they have in

this small connector. This can cause 28V VBUS to be

shorted to the CC and SBU pins. Also due to the

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

is a heightened concern that debris and moisture will

cause the 28V VBUS pin to be shorted to the CC, SBU,

or USB2 pins.

These non-ideal equipments and mechanical events

make it necessary for the CC and other pins to

be 28V tolerant, even though the pins only operate

at 5V or lower. The TPD4S201-Q1 enables the CC

and SBU or USB2 pins to be 28V 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. For systems not utilizing alternate

modes with SBU communication, the SBU pins of

the TPD4S201-Q1 can be used to protect the USB2

data lines instead. 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 external pins.

The TPD4S201-Q1 integrates IEC 61000-4-2 ESD

protection for the CC1, CC2, SBU1, and SBU2 pins,

eliminating the need to place high voltage TVS diodes

externally on the connector.
