Enabling Energy Efficient Solutions Circuit Protection Solutions Providing a comprehensive portfolio ofESD and EMI/RFI protection devices from ON Semiconductor.

Introduction Electro-Static Discharge protection and Electro-Magnetic Interference is becoming an increasingly important consideration for all electrical devices. Increased feature sets demanded by consumers, and sleek industrial designs require an increased attention to the performance of ESD and EMI in small outline packages. External Protection Requirement Advanced system-on-chip (SOC) designs are being manufactured in the most advanced technologies. In order to optimize functionality and chip size, designers are constantly reducing the minimum feature sizes within their designs. But at what...

TLP creates l-V curves in which each data point is obtained with a square pulse that closely matches an ESD event in terms of current shape and pulse width. TLP pulse lengths are typically 100 ns, with pulse amplitudes up to 40 A. Sample TLP l-V curves are shown in Figure 3, comparing an ON Semiconductor product with a competitor's product intended for the same application. The ON Semiconductor product turns on at a lower voltage and has significantly lower dynamic resistance than the competitor's device. The TLP l-V curves and parameters extracted from them can be used to compare the properties...

Enabling Energy Efficient Solutions Because of their material make up, some passive devices tend to be inconsistent over temperature and therefore less reliable in harsh environments. Maintaining Signal Integrity ESD and EMI solutions are there to protect against unwanted signals that interfere with the overall system performance. During a system's normal operation, protection devices must not degrade signal integrity. In other words, they have to be completely transparent. It is important to demonstrate that protection products do not degrade signal integrity. ON Semiconductor uses several methods...

standard. Protection for this interface consists of ensuring that transverse (metallic or differential) surge strikes do not damage sensitive downstream chips such as PHYs. This is achieved by connecting shunt protection elements from line-to-line (for each pair of lines) that transfer the incoming hostile surge energy back towards the source. -3dB cutoff frequency 0 apass a3dB Pass Band Stop Band Magnitude (dB) astop Transition Band 100k 1M 10M 100M 1G 10G 100G Frequency (Hz) Figure 8.
