STEF12PUR, Контроллер горячей замены, жесткие диски и массивы, приставки, приводы, 12В вход, DFN-10

The STEF12PUR is an Integrated Electronic Fuse optimized for monitoring output current and input voltage. Connected in series to a 12V 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 signaled to the board monitoring circuits through a signal on the Fault pin.
