Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.++## Pinout++| Pin | Name | Type | Function |+|---|---|---|---|+| 1 | ISENSE | input | Current sense input. Connect resistor RS from this pin to VIN to define nominal average output current: IOUT_NOM = 0.1/RS. Mean sense threshold voltage is 100mV (typ). |+| 2 | GND | power_in | Ground (0V). |+| 3 | GND | power_in | Ground (0V). |+| 4 | VSET | input | Multi-function On/Off, brightness control, and soft-start pin. Leave floating for normal operation. Drive below 0.2V to disable output (shutdown). DC voltage 0.3V-2.5V provides analog dimming (5%-100% of IOUT_NOM linear range). Accepts PWM signal (open-collector/drain) for 1%-100% dimming at f < 500Hz. A capacitor from VSET to GND sets soft-start time (default 0.1ms; ~1.5ms per 1nF). |+| 5 | LX | output | Switch node - drain of internal 40V NDMOS switch (RON = 0.2Ω typ). Connect to inductor and Schottky freewheeling diode. Current limit 2A typ. |+| 6 | LX | output | Switch node - drain of internal 40V NDMOS switch (RON = 0.2Ω typ). Connect to inductor and Schottky freewheeling diode. Current limit 2A typ. |+| 7 | N/C | unconnected | No Connection. |+| 8 | VIN | power_in | Input voltage supply, 4.5V to 40V (abs max 42V). Decouple to GND with 10µF or higher X7R ceramic capacitor close to the device. |+| EP | EP | passive | Exposed thermal pad. Connect to GND and thermal mass for improved thermal impedance. Should not be used as an electrical ground conduction path. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Diodes Incorporated |+| Package | MSOP-8-EP |+| Category | LED-drv |+| Pins | 9 |++## Ordering variants++- `AL8861QMP-13`++## CAD (KiCad official)++- Symbol: `AL8861QMP-13`+- Footprint: `Package_SO:MSOP-8-1EP_3x3mm_P0.65mm_EP1.5x1.8mm`+- 3D model: MSOP-8-EP (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Diodes Incorporated datasheet](docs/al8861qmp-13-datasheet.pdf) (15 pp, sha256 `c6a5a3dadc3a438c`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
