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 | VDD | power_in | Chip supply pin. Operating range 2.5 V to 6 V; absolute max 7 V. Recommend ~4.7 µF filter capacitor placed close to VDD and GND. Quiescent current ~60 µA typ. |+| 2 | DIM | input | PWM dimming input. Logic high enables LED output; logic low turns LED output off. VIH ≥ 0.7*VDD, VIL ≤ 0.3*VDD. Max dimming frequency 10 kHz (≤1 kHz recommended for best linearity). |+| 3 | NC | unconnected | No connection. Leave floating. |+| 4 | LED | output | Drain of the internal 30 V, 50 mΩ NMOS; connects to the LED cathode. Absolute maximum voltage -0.3 V to 30 V. The exposed thermal pad of the ESOP-8 is internally connected to this pin. |+| 5 | CS | input | Current-sense input. Connect through an external sense resistor Rcs to GND; the LED current is set by ILED = 100 mV / Rcs (Vcs = 96/100/104 mV min/typ/max). Absolute max voltage -0.3 V to 7 V. |+| 6 | CS | input | Current-sense input (paralleled with pin 5). Both pins tie to Rcs to GND to set output current. Use short, wide traces to minimize parasitic resistance error. |+| 7 | NC | unconnected | No connection. Leave floating. |+| 8 | GND | power_in | Chip ground reference. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | XDS |+| Package | ESOP-8 |+| Category | LED-drv |+| Pins | 8 |++## CAD (KiCad official)++- Symbol: `TX6410B`+- Footprint: `Package_SO:SOIC-8-1EP_3.9x4.9mm_P1.27mm_EP2.41x3.3mm`+- 3D model: ESOP-8 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [XDS datasheet](docs/tx6410b-datasheet.pdf) (6 pp, sha256 `7971d684c21714c4`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
