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 E-

fuse 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.
