USBLC6-2
VERY LOW CAPACITANCE
ESD PROTECTION
ASD
(Application Specific Devices)
MAIN APPLICATIONS
■
USB2.0 ports at 480Mbps (high speed) and
USB OTG ports
■
Backwards Compatible with USB1.1 Low and
full speed
■
Ethernet port: 10/100Mb/s
■
SIM card protection
■
Video line protection
■
Portable and mobile electronics
DESCRIPTION
The
USBLC6-2P6
and
USBLC6-2SC6
are two
monolithic Application Specific Devices dedicated
to ESD protection of high speed interfaces such as
USB2.0, Ethernet links and Video lines.
The very low line capacitance secures a high level
of signal integrity without compromising in
protection sensitive chips against the most
stringent characterized ESD strikes.
FEATURES
■
2 data lines protection
■
Protects V
BUS
■
Very low capacitance: 3.5pF max
■
Very low leakage current: 1µA max
■
SOT-666 and SOT23-6L packages
■
RoHS compliant
BENEFITS
■
Very low capacitance between lines to GND for
optimized data integrity and speed
■
Ultra low PCB space consuming: 2.9mm² max
for SOT-666 package and 9mm² max for
SOT23-6L package
■
Enhanced ESD protection: IEC61000-4-2 level
4 compliance guaranteed at device level,
hence greater immunity at system level
■
ESD protection of V
BUS
. Allows ESD current
flowing to Ground when ESD event occurs on
data line
■
High reliability offered by monolithic integration
■
Very low leakage current for longer operation
of battery powered devices
■
Fast response time
■
Consistant D+/D- signal balance
- Best capacitance matching tolerance I/O to
GND of 0.04pF
- Compliance with USB2.0 requirement (<1pF)
