STEF512SRDB - Dual eFuse

Description

The STEF512SRDB 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.

Features

  • 5 V and 12 V channels into one chip.
  • 25 V absolute maximum input voltage.
  • Precise output overvoltage clamp.
  • Fixed overcurrent protection trip points.
  • Fast reverse current protection on 5 V channel.
  • Thermal protection.
  • Latch-off thermal protection.
  • Input undervoltage lockout.
  • Adjustable output voltage slew rate for each channel by external capacitors.
  • Integrated 40 mΩ power MOSFETs.
  • 100 ms safety s.
