The TPS1686x is an integrated high current circuit protection and power management device. The device provides multiple protection modes using very few external components and is a robust defense against overloads, short circuits and excessive inrush current. Applications with particular inrush current requirements can set the output slew rate with a single external capacitor. Output current limit level can be set by user as per system needs. A user adjustable overcurrent blanking timer allows systems to support transient peaks in the load current without tripping the eFuse. An integrated fast and accurate sense analog load current monitor facilitates predictive maintenance and advanced dynamic platform power management such as Intel PSYS and PROCHOT to optimize server and data-center performance.
The devices are characterized for operation over a junction temperature range of –40°C to +125°C.
