USBLC6-2
VERY LOW CAPACITANCE
ESD PROTECTION
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)
