The 2:1 input ratio means it manages two input sources and one output, selecting whichever is higher. That 15 µA supply current is the chip's own draw regardless of load current — the external FET handles the heavy lifting. In a handheld device that sleeps most of the time, the quiescent loss from the selector itself stays well under the battery's self-discharge floor. The 2.5 V to 28 V supply range covers single-cell Li-ion up through multi-cell packs and USB-C PD rails. ## Package, temperature grade, and where it fits Housed in a TSOT-23-6, the same footprint as a standard SOT-23-6 but thinner — the 'T' in TSOT. The -40°C to 85°C operating range covers commercial and industrial ambient; if you need the -40°C to 125°C extended range, the 'H' variant (LTC4412HS6#TRMPBF) is the drop-in with the same pinout and timing. Target applications are handheld and USB-powered supplies — think a portable instrument that charges from USB and runs off a Li-ion pack, or a router that falls back to battery when the wall wart drops. The 110 µs turn-on delay and 13 µs turn-off delay are fast enough to prevent the output from glitching during source transitions but slow enough to avoid ringing from the external FET gate capacitance. ## Active production and sourcing posture LTC4412IS6#TRMPBF carries an active lifecycle status and is ROHS3 compliant. It's quoted to order against the BOM quantity — availability and current pricing confirmed at RFQ. The closest functional peer is the LTC4412ES6#TRPBF — same PowerPath series, same P-channel FET type, same 2:1 ratio, same 110 µs / 13 µs delays. The difference is the 'I' vs 'E' temperature grade suffix; the 'I' (industrial) is -40°C to 85°C, the 'E' (extended commercial) is 0°C to 70°C. If your BOM was specced around the 'E' grade, the 'I' grade drops into the same TSOT-23-6 footprint with wider temp margin.","metaTitle":"LTC4412IS6#TRMPBF Source Selector Switch, 2.5-28V, TSOT-23-6","metaDescription":"LTC4412IS6#TRMPBF PowerPath source selector switch, 2.5-28V supply, 15µA quiescent current, P-channel FET, active production, ROHS3.
