TPD4S311, TPD4S311A USB Type-C^™Port Protector: Short-to-V_BUSOvervoltage

and IEC ESD Protection

These non-ideal equipments and mechanical events

1 Features

make it necessary for the CC and SBU pins to be

20-V tolerant, even though the pins only operate at 5

V or lower. The TPD4S311 enables the CC and SBU

pins to be 20-V tolerant without interfering with normal

operation by providing over-voltage 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 external pins. The TPD4S311

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.

3 Description

The TPD4S311 is a single-chip USB Type-C port

protection device that provides 20-V Short-to-V_BUS

overvoltage and IEC ESD protection.

Battery

DC/DC

FET

OVP

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. One example of this is USB Type-C

Power Delivery adaptors that only place 20 V on the

V_BUSline. 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 20-V V_BUSto

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 20-V V_BUSpin to be shorted to the CC and

SBU pins.
