STEF512SRXCPUR - Dual electronic fuse for 5V and 12V rails with reverse current blocking

Product Description

STEF512SRXCPUR 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 inrush 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.
