The TPS1685x 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.
Multiple TPS1685x devices can be connected in parallel to increase the total current capacity for high power systems. All devices actively synchronize the operating state and share current during start-up as well as steady state to avoid over-stressing some of the devices which can result in premature or partial shutdown of the parallel chain.
The devices are characterized for operation over a junction temperature range of –40°C to +125°C.
