The RT1989 provides an ideal diode reverse current blocking function with low forward voltage and an enable input for disconnection. The 3.4V to 53V input operating range and 8A continuous current rating make the RT1989 well suited for multi-port USB-C sinkcurrent applications. In addition, this part includes a 60V Absolute Maximum Rating (AMR), a 20A peakcurrent 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 highcapacitance loads. Short-circuit protection is provided during this period, while the integrated MOSFETprovides a low forward voltage drop and high Safe Operating Area (SOA).The RT1989 is available in a VDFN-20TL 5.2x4 package and can operate over a junction temperature range of -40°C to 125°C.
