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, and reverse 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.
