TM512BCE from TM Shenzhen Titan Micro Elec, in a SSOP-10. 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. |
