ESD protection IC from ST Micro for data
and video interface ports
ST Microelectronics has unveiled ESD protection IC for
use with high speed multimedia and storage interconnects
such as HDMI, DisplayPort, USB 3.0, Serial ATA (SATA) and
DVI. These ESD protection devices protect four data lines
from ESD. Available in 1x2mm-outline package saves at least
30% of PCB space compared to other devices, says ST Micro.
As these high-speed interconnect standards specify convenient,
miniaturized connectors and cables the users can easily
connect and disconnect devices such as video equipment,
terabyte storage, multi-megapixel cameras, and smartphones
but here in lies the risk of damage to the internal circuitry
by Electrostatic Discharges (ESD). By providing a convenient
one-chip ESD-protection solution, ST's HSP061-4NY8 addresses
a large and important market. The HSP061-4NY8 provides the
industry with a single orderable part capable of protecting
circuits using any of these multi-gigabit standards, enabling
economies of scale as well as significant advantages in
efficiency throughout product design, purchasing, and assembly.
The device contains a network of Transient Voltage Suppression
(TVS) diodes capable of protecting two pairs of high-speed
differential data lines. These diodes are sufficient to
provide complete protection for the 5.0 Gbit/s SuperSpeed
bus defined in the new USB 3.0 specification. A single HSP061-4NY8
can also protect all the data lines of an HDMI port, an
entire channel in SATA interfaces, up to and including the
latest 6Gbit/s SATA 3.0 standard, or a two-lane DisplayPort
interface.
Technical features of the HSP061-4NY8:
ESD protection complying with: IEC61000-4-2 level 4 (8kV
air discharge) and MIL-STD 883G Method 3015-7 Class 3B (>8kV)
Ultra low capacitance: 0.6pF
5.8GHz bandwidth and 100 Ohm differential impedance: suitable
for 3.4Gbit/s data lines
Low leakage current: 100nA at 25°C
0.55mm-high 1x2mm 8-lead microDFN package
Price: HSP061-4NY8 is priced at US$0.20 in quantities of
3000
