STEF512SRX - Dual electronic fuse

General Description

The STEF512SRX 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.

Key Features

  • 5 V and 12 V channels into one chip.
  • 25 V absolute maximum input voltage.
  • Precise output overvoltage clamp.
  • Fixed overcurrent protection for both channels.
  • Reverse current protection on 5 V channel.
  • Thermal protection.
  • Available in auto-retry version.
  • Input undervoltage lockout.
  • Adjustable output voltage slew rate.
  • Integrated 45 mΩ power MOSFETs.
  • SAS disable pin.
  • Current monitor pin selec.
