STEF12S Datasheet (STMicroelectronics)

STEF12S, Electronic fuse

The STEF12S is an integrated electronic fuse optimized to monitor the 12 V DC power lines.

When connected in series to the main power rail, it is able to precisely detect and react to overcurrent and overvoltage conditions.

When an overload condition occurs, the device limits the output current to a
