The TPS25984Bx is a high-current, stackable integrated hotswap protection (eFuse) device in a small package. 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. Internal overcurrent blanking timer allows systems to support transient peaks in the load current without tripping the eFuse.

Multiple TPS25984Bx devices can be stacked in parallel to increase the total current capacity for high power systems. All devices share current during start-up to avoid over-stressing some of the devices which can result in premature or partial shutdown of the parallel chain.

An integrated fast and accurate sense analog load current monitor facilitates predictive maintenance and advanced dynamic platform power management techniques such as Intel PSYS and PROCHOT™ to maximize system throughput and power supply utilization.

The devices are characterized for operation over a junction temperature range of –40°C to +125°C.
