IP4234CZ6
Single USB 2.0 ESD protection to IEC 61000-4-2 level 4
Rev. 01 — 16 April 2009
Product data sheet
1. Product profile
1.1 General description
The IP4234CZ6 is 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 ±8 kV 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.
The IP4234CZ6 is fabricated using monolithic silicon technology and integrates two
ultra-low capacitance π-filter ESD protection diodes plus a Zener diode in a miniature
6-lead SOT457 package.
