Description
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...
