The STEF512SRI is an integrated dual electronic fuse, designed to protect circuitry on the output from overcurrent and overvoltage events, in those applications requiring hot swap operation and in-rush current control.
The device embeds two electronic fuses, one for the 5 V rail and one for the 12 V rail. Thanks to the very low ON-resistance of the integrated power MOSFETs, the voltage drop from the main supply to the load is very low during normal operation.
The 5 V channel provides a reverse blocking feature, preventing current flow to the input in case of brown-out or shutdown.
Startup time is internally controlled by a dedicated slew-rate circuit. In this way the inrush current at startup can be kept under control.
The maximum load current is precisely limited, by utilizing a sense FET topology, to factory-defined values.
The device also provides precise overvoltage clamp for each channel, preventing the load from being damaged by power supply failures, and Under Voltage Lockout (UVLO), assuring that the input voltage is above the minimum operating threshold before the power device is turned on.
When an overload condition occurs, the STEF512SRI limits the output current to the predefined safe value. If the anomalous overload condition persists, the device goes into thermal shutdown, the internal switch opens, and the load disconnected from the power supply. Load current on each channel can be precisely monitored by reading the signal on the IMON_5/12 pin.
The device features a SATA– Ignore pin, that can be used to simplify compatibility among SAS/SATA interfaces.
