产品概述

描述

The STEF05L is an integrated electronic fuse optimized for monitoring output current and the input voltage. Connected in series to the 5 V rail, it is able to protect the electronic circuitry on its output from overcurrent and overvoltage. 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. 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. The voltage clamping circuit prevents the output voltage from exceeding a fixed value, if the input voltage goes beyond this threshold. The device is equipped with a thermal protection circuit. Intervention of thermal protection is signaled to the board-monitoring circuits through an appropriate signal on the Fault pin. Unlike mechanical fuses, which must be physically replaced after a single event, the eFuse does not degrade in its performances following short-circuit/thermal protection intervention and is reset either by re-cycling the supply voltage or using the appropriate Enable pin. The STEF05L is also available in an autoretry version; in case of thermal fault it automatically attempts to re-apply power to the load when the die temperature returns to a safe value.
