# LP5810ADSDR

**Texas Instruments** · LED Drivers(RGB) · WSON-8-EP(3x3)

LP5810ADSDR from Texas Instruments, in a WSON-8-EP(3x3). 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 | VCC | power_in | Supply voltage input, 2.7V to 5.5V range; place 22µF bypass capacitor as close as possible to this pin and GND. |
| 2 | SYNC | bidirectional | I/O pin for synchronization clock between multiple devices; ground to disable and save power. |
| 3 | SCL | input | I2C serial interface clock input; accepts logic levels from 0.4V (low) to 1.4V (high minimum). |
| 4 | SDA | bidirectional | I2C serial interface data input/output; accepts logic levels from 0.4V (low), outputs 0.4V typical when low. |
| 5 | OUT3 | output | LED current sink output 3; sources 0.1mA to 51mA depending on MC bit and DC register settings; leave floating when not used. |
| 6 | OUT2 | output | LED current sink output 2; sources 0.1mA to 51mA depending on MC bit and DC register settings; leave floating when not used. |
| 7 | OUT1 | output | LED current sink output 1; sources 0.1mA to 51mA depending on MC bit and DC register settings; leave floating when not used. |
| 8 | OUT0 | output | LED current sink output 0; sources 0.1mA to 51mA depending on MC bit and DC register settings; leave floating when not used. |
| 9 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
