3 Description

The TPS25925x/6x family of eFuses is a highly

integrated circuit protection and power management

solution in a tiny package. The devices use few

external components and provide multiple protection

modes. They are a robust defense against overloads,

shorts circuits, voltage surges, excessive inrush

current. Current limit level can be set with a single

external resistor and current limit set has a typical

accuracy of ±15%. Over voltage events are limited by

internal clamping circuits to a safe fixed maximum,

with no external components required. TPS25926x

devices provide over voltage protection (OVP) for 12-

V systems and TPS25925x devices for 5-V systems.

In cases with particular voltage ramp requirements, a

dV/dT pin is provided that can be programmed with a

single capacitor to ensure proper output ramp rates.
