TM512AC from TM Shenzhen Titan Micro Elec, in a SOP-16. 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 (0 V). All internal logic and current-sink outputs reference this pin. |
| 2 | OUTR | output | Constant-current PWM output for the Red LED channel. 16-bit / 65536-level grayscale open-drain sink; withstand voltage >30 V, programmable current up to 80 mA (set by REXT). |
| 3 | OUTG | output | Constant-current PWM output for the Green LED channel. 16-bit grayscale open-drain sink; withstand voltage >30 V, current programmed via REXT (max 80 mA). |
| 4 | OUTB | output | Constant-current PWM output for the Blue LED channel. 16-bit grayscale open-drain sink; withstand voltage >30 V, current programmed via REXT (max 80 mA). |
| 5 | OUTW | output | Constant-current PWM output for the White LED channel. 16-bit grayscale open-drain sink; withstand voltage >30 V, current programmed via REXT (max 80 mA). |
| 6 | REXT | passive | Constant-current feedback / reference. Connect an external resistor to GND to program the OUTR/G/B/W sink current. Iout = 48/(400+Rext); e.g. 2266.67 Ω → 18 mA, 400 Ω → 60 mA. Max Iout 80 mA. |
| 7 | ADRO | output | Address-write daisy-chain OUTPUT. During address programming this pin cascades to the ADRI of the next IC on the chain. Push-pull; Iol/Ioh ≥ 10 mA. |
| 8 | SET | input | Power-on RGBW state setting pin. Leave floating → OUTB drives 5% grayscale on power-up; tie to VDD → all channels off. Configures the default startup output pattern. |
| 9 | NC | unconnected | No connection. Leave floating. |
| 10 | ADRI | input | Address-write daisy-chain INPUT with internal pull-up. Receives the address-programming signal from the previous IC's ADRO (or from the programmer for the first IC). |
| 11 | AI | input | Positive (non-inverting) input of the differential DMX512 receiver. Internal pull-up. Input common-mode range up to 8 V; differential threshold ±0.2 V; input impedance ~280 kΩ. |
| 12 | BI | input | Negative (inverting) input of the differential DMX512 receiver. Internal pull-down. Pair with AI for RS-485-style DMX512 signaling at 200 kbps-1 Mbps. |
| 13 | PWM | input | Output-polarity select. Leave floating for normal polarity; tie to VDD to invert output polarity (also lowers refresh rate to 250 Hz). Used when driving PNP/PMOS boost stages for high-current channels. |
| 14 | NC | unconnected | No connection. Leave floating. |
| 15 | NC | unconnected | No connection. Leave floating. |
| 16 | VDD | power_in | Logic supply positive. Recommended 3.8-6 V (typ 5.5 V, abs-max +6.5 V). Datasheet notes an internal 5 V regulator/clamp diode; decouple to GND with a bulk + 0.1 µF ceramic. |
