STMicroelectronics STEF05D
The STEF05D is an integrated electronic fuse optimized for monitoring output current and input voltage. The device has a controlled delay and turn-on time. When an overload condition occurs, the STEF05D limits the output current to a predefined safe value.| Part No. | STEF05D |

DESCRIPTION
Connected in series to a 5 V rail, it is capable of protecting the electronic circuitry on its output from overcurrent and overvoltage. 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 signal led to the board monitoring circuits through a signal on the Fault pin.
