3 Description

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 datacenter

performance.

The devices are characterized for operation over a

junction temperature range of –40°C to +125°C.
