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 | GND | power_in | Power supply negative (ground) reference for the logic and constant-current output stages. |+| 2 | OUTR | output | PWM constant-current output channel R. Open-drain sink, withstand >30 V, programmable 3-80 mA set by REXT, 16-bit gamma-corrected grayscale. |+| 3 | OUTG | output | PWM constant-current output channel G. Open-drain sink, withstand >30 V, programmable 3-80 mA set by REXT, 16-bit gamma-corrected grayscale. |+| 4 | OUTB | output | PWM constant-current output channel B. Open-drain sink, withstand >30 V, programmable 3-80 mA set by REXT, 16-bit gamma-corrected grayscale. |+| 5 | REXT | passive | Constant-current feedback / current-set pin. External resistor to GND programs the per-channel output current per Iout=48/(400+Rext); must not be left floating. |+| 6 | ADRO | output | Address programming line output. Push-pull output used to daisy-chain the address-writing signal to the next IC on the string. Drives at least ±10 mA at Vo=0.4 V / 4.0 V. |+| 7 | ADRI | input | Address programming line input with internal pull-up. Receives the address-write signal from the writer/controller or from the previous chip's ADRO in a chain. |+| 8 | AI | input | DMX512 differential signal input, positive polarity, with internal pull-up. Common-mode range up to 8 V, differential input impedance ~280 kΩ, threshold ±0.2 V, 70 mV hysteresis. |+| 9 | BI | input | DMX512 differential signal input, negative polarity, with internal pull-down. Paired with AI for the DMX512 differential receiver (auto-adaptive 200 kbps-1 Mbps). |+| 10 | VDD | power_in | Logic supply positive input. Recommended 3.8 V (min) / 5.5 V (typ) / 6 V (max); absolute max 6.5 V. Internal 5 V regulator/zener present; decouple with 104 (100 nF) to GND per application note. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | TM Shenzhen Titan Micro Elec |+| Package | SSOP-10 |+| Category | LED Drivers |+| Pins | 10 |++## CAD (KiCad official)++- Symbol: `TM512BCE`+- Footprint: `Package_SO:SSOP-10_3.9x4.9mm_P1.00mm`+- 3D model: SSOP-10 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [TM Shenzhen Titan Micro Elec datasheet](https://jlcpcb.com/api/file/downloadByFileSystemAccessId/8590923800940650496) (None pp, sha256 `d1648071c9328d6b`, retrieved 2026-08-17, tier: lcsc)+- **Datasheet language:** Chinese.
