STMicroelectronics STEF05L
The STEF05L is an integrated electronic fuse optimized for monitoring output current and the input voltage. The STEF05L has controlled delay and turn-on time. When an overload condition occurs, the device limits the output current to a predefined safe value.| Part No. | STEF05L |

DESCRIPTION
Connected in series to the 5 V rail, it is able to protect 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 the power is re-applied the eFuse initially limits the output current to a safe value and then goes again into the open state.
