TPS25961 can be used for input power protection in set-top boxes. Operating voltage is generally around 12-V and can vary from 10-V to 14-V. During event like input voltage overshoot, TPS25961 overvoltage protection acts to cut off the path and protect downstream load from overvoltage. Also inrush current control and configurable current limit feature helps in preventing power supply from collapsing during events like hotplug and overload.
