Description
The STEVAL-IFP021V1 demonstration board is
based on the STEF05 and STEF12 electronic
fuses (E-Fuses).
It is designed to help users evaluate the benefit of
the complete protection offered by the E-Fuse
family and to customize their own application.
The E-Fuse family of hot-swap converters is
designed to replace the mechanical fuses on low
voltage power lines.
The STEF05 and STEF12 are integrated
electronic fuses optimized for monitoring output
current and input voltage.
Connected in series to the 5 V/12 V rails, they are
capable of protecting the electronic circuitry on
the output from overcurrent and overvoltage.
The turn-on time is programmable by means of an
external capacitor, allowing control of the inrush
current at startup and during hot-swaps.
When an overload condition occurs, the E-Fuse
limits the output current to a predefined safe
value. If the anomalous overload condition

persists, it goes into an open state, disconnecting
the load from the power supply.
If a continuous short-circuit is present on the
board, when power is re-applied the E-Fuse
initially limits the output current to a safe value,
and then again goes into an open state.
Both devices are equipped with a thermal
protection circuit.
The intervention of the thermal protection is
signaled to the board monitoring circuits through
a signal on the enable/fault pin that can be
connected to other parts belonging to the same
family to cause a simultaneous shutdown during
failure events.
Unlike mechanical fuses, which must be
physically replaced after a single event, E-Fuses
do not degrade in their performance after short-
circuit/thermal protection interventions and can be
reset either by re-cycling the supply voltage or by
using the enable pin.
