IP4220CZ6

Dual USB 2.0 integrated ESD protection to IEC 61000-4-2 level 4

Rev. 04 — 12 September 2005	Product data sheet

1.Product profile

1.1General description

The IP4220CZ6 is designed to protect I/O lines sensitive to capacitive load, such as USB 2.0, ethernet, DVI etc. from damage due to ElectroStatic Discharge (ESD). It incorporates four pairs of ultra-low capacitance rail-to-rail diodes plus an additional Zener diode to provide protection to signal and supply components from ESD voltages as high as ±8 kV contact discharge. Protection is supply voltage independent due to the rail-to-rail diodes being connected to the Zener diode. The IP4220CZ6 integrates four pairs of ultra-low capacitance rail-to-rail ESD protection diodes in a miniature 6-lead SOT457 package.

7.Application information

7.1Universal serial bus 2.0 protection

The IP4220CZ6 is optimized to protect, for example, two USB 2.0 ports from ESD. Each device is capable of protecting both USB data lines and the VBUS supply. A typical application is shown in Figure 1.
