TLC59401RHBR from Texas Instruments, in a VQFN-32-EP(5x5). Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | SCLK | input | Serial data shift clock for synchronizing serial input transfers. |
| 2 | SIN | input | Serial data input for shifting grayscale or dot correction data into the device. |
| 3 | MODE | input | Input mode-change pin; when MODE = GND, device is in GS mode; when MODE = VCC, device is in DC mode. |
| 4 | OUT0 | output | Constant-current output; multiple outputs can be configured in parallel to increase constant-current capability; different voltages can be applied to each output. |
| 5 | OUT1 | output | Constant-current output. |
| 6 | OUT2 | output | Constant-current output. |
| 7 | OUT3 | output | Constant-current output. |
| 8 | OUT4 | output | Constant-current output. |
| 9 | OUT5 | output | Constant-current output. |
| 10 | OUT6 | output | Constant-current output. |
| 11 | OUT7 | output | Constant-current output. |
| 12 | NC | unconnected | No connection. |
| 13 | NC | unconnected | No connection. |
| 14 | OUT8 | output | Constant-current output. |
| 15 | OUT9 | output | Constant-current output. |
| 16 | OUT10 | output | Constant-current output. |
| 17 | OUT11 | output | Constant-current output. |
| 18 | OUT12 | output | Constant-current output. |
| 19 | OUT13 | output | Constant-current output. |
| 20 | OUT14 | output | Constant-current output. |
| 21 | OUT15 | output | Constant-current output. |
| 22 | XERR | output | Error output; XERR is an open-drain terminal; XERR goes low when LOD or TEF is detected. |
| 23 | SOUT | output | Serial data output for cascading multiple devices. |
| 24 | GSCLK | input | Reference clock for grayscale PWM control. |
| 25 | TEST | input | Test pin; TEST must be connected to VCC. |
| 26 | IREF | input | Reference current terminal; maximum current for outputs OUT0-OUT15 is set with a resistor from IREF to GND. |
| 27 | VCC | power_in | Power-supply voltage; 3.0 V to 5.5 V. |
| 28 | NC | unconnected | No connection. |
| 29 | NC | unconnected | No connection. |
| 30 | GND | power_in | Ground. |
| 31 | BLANK | input | Blank all outputs; when BLANK is high, all OUTn outputs are forced OFF and GS counter is reset; when BLANK is low, OUTn are controlled by grayscale PWM control. |
| 32 | XLAT | input | Level triggered latch signal; when XLAT is high, writes data from input shift register to GS register (MODE low) or DC register (MODE high); when XLAT is low, data in registers are held constant. |
| 33 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
