3 Description
The TPD2S300 is a single chip USB Type-C port
protection solution that provides 20-V Short-to-V_BUS
overvoltage and IEC ESD protection for the CC1 and
CC2 pins.
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 start out with 20 V on
the V_BUS line. 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_BUS to be
shorted to the CC pins. Also, due to the close
proximity of the pins in the Type-C connector, there is
a heightened concern that debris and moisture is
going to cause the 20-V V_BUS pin to be shorted to the
CC pins.
These non-ideal equipments and mechanical events
make it necessary for the CC pins to be 20-V
tolerant, even though they only operate at 5 V or
lower. The TPD2S300 enables the CC pins to be 20-
V tolerant without interfering with normal operation by
providing overvoltage protection on the CC pins. The
device places high voltage FETs in series on the 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 IEC61000-4-2 system
level ESD protection for their external pins. The
TPD2S300 integrates IEC 61000-4-2 ESD protection
for the CC1 and CC2 pins, removing the need to
place high voltage TVS diodes externally on the
connector.
