ECLAMP2522P.TCT

The ECIamp2522P 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 ECIamp2522P 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.
