LTC4412ES6#TRMPBF from Analog Devices, in a TSOT-23-6L. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VIN | power_in | Primary input supply voltage that powers the internal circuitry and is one of two voltage sense inputs, and it can be bypassed to ground with 0.1µF to 10µF to suppress load transients. |
| 2 | GND | power_in | Ground pin that provides the power return for all internal circuits. |
| 3 | CTL | input | Digital control input where a logic high (VIH) forces the primary MOSFET gate-to-source voltage to a small value (VGOFF) and forces STAT to sink 10µA, with a 3.5µA internal pull-down holding it low when open and a 0.35V VIL threshold. |
| 4 | STAT | output | Open-drain status output that is open in forward regulation and sinks 10µA (IS(SNK)) in reverse turn-off or when CTL is high, and it can be biased from ground to 28V regardless of the supply voltage. |
| 5 | GATE | output | Gate drive output for the primary P-channel MOSFET that regulates a 20mV forward voltage between VIN and SENSE and is clamped about 7V (VG(ON)) below the higher of VIN or SENSE. |
| 6 | SENSE | power_in | Power sense input that supplies power to internal circuitry and is the second voltage sense input, usually fed from an auxiliary source such as an AC adapter or back-up battery. |
