LM3485MM from Texas Instruments, 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 | ISENSE | input | Current sense input pin; should be connected to drain node of external PFET. |
| 2 | GND | power_in | Signal ground. |
| 3 | NC | unconnected | No connection. |
| 4 | FB | input | Feedback input; connect to resistor voltage divider between output and GND for adjustable output voltage. |
| 5 | ADJ | input | Current limit threshold adjustment pin; connects to internal 5.5-µA current source with external resistor to input power supply; voltage across resistor compared with PFET VDS to determine over-current condition. |
| 6 | PWR GND | power_in | Power ground. |
| 7 | PGATE | output | Gate drive output for external PFET; PGATE swings between VIN and VIN-5 V. |
| 8 | VIN | power_in | Power supply input pin; 4.5 V to 35 V operating range. |
