3 Description
The TPS25985x 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.
