EClamp2522P
USB Upstream Port Filter and TVS
For EMI Filtering and ESD Protection
PROTECTION PRODUCTS - EMIClamp^TM
PRELIMINARY
Description
Features
The EClamp^TM2522P is an easily implemented solution
for protection and termination of low speed or full
speed Universal Serial Bus (USB) ports. Each device will
provide termination, filtering, and ESD protection for
one upstream USB port on cellular phones and other
portable electronics. This state-of-the-art device utilizes
solid-state silicon-avalanche technology for superior
clamping performance and electrical characteristics.
Line termination is achieved with 22 Ohm series
resistors on both the D+ and D- USB lines. TVS diodes
are also included on each data line for ESD protection
in excess of ±15kV (air discharge) and ±8kV (contact
discharge) per IEC 61000-4-2, level 4. An additional
TVS diode connection is included for protection of the
voltage (VBus) bus. The 1.5k Ohm pull-up resistor is
included on one of the USB data lines to identify the
equipment as either a full-speed (connected to D+ line)
or low-speed (connected to D- line) device.

The EClamp2522P is in a 6-pin, RoHS compliant,
SLP1616P6 package. It measures 1.6 x 1.6 x
0.60mm. The leads are spaced at a pitch of 0.5mm
and are finished with lead-free NiPdAu. The small
package makes it ideal for use in portable electronics
such as cell phones and digital still cameras.
