23V/8A Ideal Diode Protection Switch

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. Short-circuit protection is provided during this period, while the integrated MOSFET provides a low forward voltage drop and high Safe Operating Area (SOA).The RT1985 is available in a VDFN-12TL 3x3 package and can operate over -40°C to 125°C junction temperature.
