4.5-V to 16-V, 0.8-mΩ 70-A stackable eFuse with accurate and fast current monitor

The TPS25984x is an integrated, high-current circuit protection and power management solution 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. A user adjustable overcurrent blanking timer allows systems to support transient peaks in the load current without tripping the eFuse.

Multiple TPS25984x devices can be connected in

parallel to increase the total current capacity

for high power systems. All devices actively

synchronize their 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.

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.
