LTC4414IMS8#TRPBF from Analog Devices, in a MSOP-8. 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 | STAT | output | Open-drain status output that sinks IS(SNK) of at least 50µA when the reverse turn-off threshold VRTO is reached, and can be biased from ground to 36V. |
| 2 | CTL | input | Digital control input with VIH of 0.9V and VIL of 0.35V, which when high forces the primary MOSFET off and the STAT pin on; it can be biased from ground to 36V and has a 3.5µA internal pull-down. |
| 3 | GND | power_in | Ground, providing the power return for all internal circuits. |
| 4 | NC | unconnected | No connect; the datasheet pin function section gives no function for this pin. |
| 5 | NC | unconnected | No connect; the datasheet pin function section gives no function for this pin. |
| 6 | SENSE | input | Power sense input that supplies internal circuitry and serves as the voltage sense input to the analog controller, with an absolute maximum range of -14V to 40V. |
| 7 | VIN | power_in | Primary input supply voltage with an operating supply range of 3V to 36V, bypassable to ground with 0.1µF to 10µF to suppress load transients. |
| 8 | GATE | output | Gate drive output for the external P-channel MOSFET that holds 20mV forward regulation between VIN and SENSE, with the gate clamp voltage VG(ON) of 8V to 9V below VIN. |
