Description
The STEF12 is an integrated electronic fuse optimized for
monitoring output current and input voltage. Connected in series to
a 12 V rail, it is capable of protecting the electronic circuitry
on its output from overcurrent and overvoltage. The device has a
controlled delay and turn-on time. When an overload condition
occurs, the STEF12 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. The device is
equipped with a thermal protection circuit. The intervention of the
thermal protection is signalled to the board monitoring circuits
through a signal on the Fault pin. Unlike the mechanical fuses,
which must be physically replaced after a single event, the Efuse
does not degrade in its performance after short-circuit/thermal
protection interventions and it is reset either by recycling the
supply voltage or using the Enable pin. The companion chip for the
5 V power rails is also available with part number STEF05.
