ON Semiconductor has introduced an electrostatic discharge (ESD) protection IC with integrated common mode choke for high-speed data line applications.
The new NUC2401MN combines high bandwidth differential filtering, solid common mode stop band attenuation and enhanced ESD protection. Enabling designers to achieve filtering and protection while realising space and cost savings, it is suitable 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 2 x 2,2 mm, the device combines common mode EMI filtering with ESD protection to ±12 – in accordance with the IEC61000-4-2 industry standard for contact discharge. Machine Model (MM) and Human Body Model (HBM) ESD ratings are 1,6 kV and 16 kV respectively. The device is rated to MSL 1 and will operate at temperatures from -40°C to 85°C.
Because the NUC2401MN is an integrated solution, it helps reduce parasitic inductance, resulting in more ideal common mode filtering. The cutoff frequency for common mode noise reduction is 40 MHz and typical common mode impedance at 100 MHz and 500 MHz is 200 Ω and 500 Ω respectively. The device also offers a low maximum clamp voltage of 10 V at a peak current of 5 A. Maximum peak pulse current rating is 19 A.
