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.
