In this section, we look at the various protections that a PSU has in order to avoid harm not only to the supply, but also to the system that it feeds with power. Many budget PSUs only have the necessary protections that the ATX specification demands (OCP, SCP, OVP), while higher-end units usually have … See more As the ATX specification states, the PSU uses a power good or PWR_OK delay signal to indicate that the +5V, +3.3 V and +12V outputs are … See more The ATX specification states that the over-voltage protection sense circuitry and reference should reside in packages that are separate and distinct from the regulator control circuitry and reference. So, no single point of … See more Over-current protection (OCP) is a popular protection found in all PSUs with multiple +12V rails, and in most cases, it also protects the minor rails. OCP kicks in when the current in the rails surpasses a certain limit. The ATX … See more The over-power protection (OPP) kicks in when the power we pull from a PSU exceeds its maximum rated capacity. Usually, the manufacturers give a little room for … See more WebThe ADG5412F overvoltage fault protected quad SPST switch that uses this type of ESD cell achieves a 5.5 kV HBM ESD rating. There may still be a requirement for an external TVS or …
