STEF512GR, Dual electronic fuse

The STEF512GR is an integrated dual electronic fuse, designed to protect circuitry on its output from overcurrent and overvoltage events, in those applications requiring hot swap operation and in-rush current control.

The device embeds two independent electronic fuses, one for the 5 V rails and one
