The IP4234CZ6 is a single USB 2.0 ESD Protection Device designed to protect input/output (I/O) USB 2.0 ports that are sensitive to capacitive loads, from being damaged by electrostatic discharge (ESD). The π-filter structure is implemented with a small series resistor to provide the necessary protection to signal and supply components from ESD voltages greater than ±8kV contact discharge according IEC 61000-4-2, level 4. The ESD protection is independent of the supply voltage due to the rail-to-rail diode architecture being connected to a Zener diode. It is fabricated using monolithic silicon technology and integrates two ultra-low capacitance π-filter ESD protection diodes plus a Zener diode.
Simple, direct signal routing provides for high speed signal integrity
Significant reduction in peak clamping and peak residual current
Four low input capacitance (2.0pF typical) rail-to-rail ESD protection diodes
Low voltage clamping due to an integrated Zener diode
