ON unveils protection IC

An ON Semiconductor product story

Edited by the Electronicstalk editorial team Jun 1, 2009

ON Semiconductor has introduced an integrated common-mode choke and electrostatic discharge (ESD) protection IC for high-speed data line applications.

The NUC2401MN combines high-bandwidth differential filtering, solid common-mode stop-band attenuation and ESD protection.

These features make this system superior to typical electromagnetic interference (EMI) filters and discrete alternatives, while helping to significantly lower component count.

Enabling designers to achieve superior filtering and protection while realising space and cost savings and improving overall reliability, it is ideal for a wide variety of applications based on high-speed differential data lines, including USB 2.0, IEEE1394, LVDS, MIPI and MDDI.

Integrating the equivalent of five discrete components into a DFN package measuring just 2mm x 2.2mm, the NUC2401MN combines common-mode EMI filtering with ESD protection to +/-12kV, in accordance with the IEC61000-4-2 industry standard for contact discharge.

Machine model (MM) and human body model (HBM) ESD ratings are 1.6kV and 16kV respectively.

The device is rated to MSL 1 and will operate at temperatures from -40C to 85C.

Because the NUC2401MN is an integrated system, it helps reduce parasitic inductance, resulting in more ideal common-mode filtering.

The cut-off frequency for common-mode noise reduction is 40MHz, and typical common-mode impedance at 100MHz and 500MHz is 200 ohms and 500 ohms respectively.

The device also offers a low maximum clamp voltage - 10V at a peak current of 5A - to ensure superior ESD protection.

Maximum peak pulse current rating is 19A.
