RT1985 - 23V/8A Ideal Diode Protection Switch

Description

The RT1985 provides an ideal diode reverse current blocking function with low forward voltage and an enable input for disconnection.

The 3.4V to 23V input operating range and 8A continuous current rating make the RT1985 well suited for multi-port USB-C sink current applications.

Features

  • 8A Continuous/20A Peak Current Capability.
  • Input Supply Voltage: 3.4V to 23V.
  • 20mΩ (typical) RON.
  • Analog Ideal Diode Gate Control.
  • Blocks Reverse Current.
  • Avoids Switch Chatter.
  • Enables Fast Power Swap.
  • Programmable Soft-Start.
  • Overvoltage Protection.
  • Over-Temperature Protection.
  • Start-Up Short-Circuit Protection.
  • Compliance with IEC 61000-4-2 and IEC 61000-45 Standards 3.

RT1985 23V/8A Ideal Diode Protection Switch 1 General Description The RT1985 provides an ideal diode reverse current blocking function with low forward voltage and an enable input for disconnection. The 3.4V to 23V input operating range and 8A continuous current rating make the RT1985 well suited for multi-port USB-C sink current applications. In addition, this part includes a 28V Absolute Maximum Rating (AMR), a 20A peak current rating (up to 10ms), undervoltage-lockout, overvoltage protection, and over-temperature protection. An adjustable soft-start circuit sets the output voltage slew rate and manages inrush current into high capacitance loads.
