TPS259474x can be used for PCIe card input power protection. A full-sized ×16 graphics card can draw up to 5.5 A at +12 V (66 W). A typical PCIe slot has the capacity of providing current up to 6 A. During overcurrent or short-circuit event at load side, TPS259474x can quickly respond to this fault event by turning off the device and thus protect the load from damage as well as prevent input supply from drooping. The ITIMER feature allows short duration peak currents to pass through without tripping the eFuse, thereby meeting the transient load current profile of graphics cards.
