It handles a supply range of 3.2V to 65V, covering 12V, 24V, and 48V rails without external pre-regulation. The controller draws 80 µA typical supply current, which keeps standby loss low in always-on ORing applications such as base-station power feeds or industrial PLC backplanes. ## Switching speed and fault response The ON delay is 1.4 µs and the OFF delay is 450 ns. The fast turn-off limits reverse current during a supply fault or short, reducing stress on the upstream MOSFET and downstream load. Because the controller does not integrate the power switch, the designer selects the external N-channel FET based on the load current and thermal budget. The 1:1 input-to-output ratio simplifies the control loop for single-channel ORing. The device is supplied in an SOT-23-8 package with a TSOT-23-8 supplier device package. The small body fits tight layouts, but the thermal pad is absent — the junction-to-ambient thermal resistance relies on the copper area on the PCB around the pins. Surface-mount assembly is standard; the tape-and-reel option supports automated pick-and-place for volume production.","metaTitle":"LM74700MDDFREP N+1 ORing Controller – TI, SOT-23-8, Active","metaDescription":"Texas Instruments LM74700MDDFREP N+1 ORing Controller, 3.2V–65V supply, 80 µA Iq, -50°C to 125°C, SOT-23-8.
