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 | Ground return for the control logic and constant-current output stages. Tie to system 0 V; IGND up to 720 mA. |+| 2 | SDI | input | Serial data input to the 16-bit shift register. Sampled on the DCLK rising edge; VIH=0.7*VDD, VIL=0.3*VDD, Schmitt-trigger input. |+| 3 | DCLK | input | Data shift clock input. Data on SDI is shifted on the rising edge; also counted while LE is high to select control commands. Up to 30 MHz at VDD=5 V (25 MHz at 3.3 V). |+| 4 | LE | input | Latch enable / data-strobe input. Combined with the number of DCLK rising edges captured while LE is high, encodes the control command (data latch, global latch, read/write status register). Internal pull-down (250-800 kOhm) to GND. |+| 5 | OUT0 | output | Constant-current LED sink output channel 0 (open-drain). Sinks 1-45 mA (VDD=5 V) or 1-30 mA (VDD=3.3 V) set by R-EXT; VDS up to 17 V. |+| 6 | OUT1 | output | Constant-current LED sink output channel 1. Programmable current per external R-EXT and 6-bit gain; PWM controlled by GCLK. |+| 7 | OUT2 | output | Constant-current LED sink output channel 2. |+| 8 | OUT3 | output | Constant-current LED sink output channel 3. |+| 9 | OUT4 | output | Constant-current LED sink output channel 4. |+| 10 | OUT5 | output | Constant-current LED sink output channel 5. |+| 11 | OUT6 | output | Constant-current LED sink output channel 6. |+| 12 | OUT7 | output | Constant-current LED sink output channel 7. |+| 13 | OUT8 | output | Constant-current LED sink output channel 8. |+| 14 | OUT9 | output | Constant-current LED sink output channel 9. |+| 15 | OUT10 | output | Constant-current LED sink output channel 10. |+| 16 | OUT11 | output | Constant-current LED sink output channel 11. |+| 17 | OUT12 | output | Constant-current LED sink output channel 12. |+| 18 | OUT13 | output | Constant-current LED sink output channel 13. |+| 19 | OUT14 | output | Constant-current LED sink output channel 14. |+| 20 | OUT15 | output | Constant-current LED sink output channel 15 (last channel; SDO shifts out from this stage). |+| 21 | GCLK | input | Grayscale clock input. Drives the 16-bit PWM comparator that generates output pulse widths; up to 33 MHz (16.5 MHz in 2x-frequency Scrambled-PWM mode) at VDD=5 V. |+| 22 | SDO | output | Serial data output; the shift-register tail. Connect to the SDI of the next MBI5043 for daisy-chaining. Push-pull output, IOH/IOL = 1 mA. |+| 23 | R-EXT | passive | External current-set resistor pin. A single resistor from R-EXT to GND programs the nominal constant-current level for all 16 outputs (e.g. ~700 Ohm for 20 mA typical characterization). |+| 24 | VDD | power_in | Logic and driver supply, 3.0-5.5 V (absolute max 7 V). Decouple with a 100 nF ceramic close to the pin. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | MBI |+| Package | SSOP-24 |+| Category | LED-drv |+| Pins | 24 |++## Ordering variants++- `MBI5043GP-AGP`+- `MBI5043GP-AGM`++## CAD (KiCad official)++- Symbol: `MBI5043GP-A`+- Footprint: `Package_SO:SSOP-24_5.3x8.2mm_P0.65mm`+- 3D model: SSOP-24 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [MBI datasheet](docs/mbi5043gp-a-datasheet.pdf) (23 pp, sha256 `81805f1814ff4a53`, retrieved 2026-08-17, tier: lcsc)+- **Datasheet language:** Chinese.
