TM1809 24bits IC for 5v/12v pixel led tapes addressable chip Components
stars, based on 0reviews
This pixel protocol was designed by Titan Micro Electronics in China. TM1809 is equipped with all the same features as its previous version, TM1803, but supports 3 RGB pixels off the one chip. The control circuit comes in a SOP14 package, allowing for more flexibility with LED choice.
TM1809 is a special IC with 9 channels(3R+3G+3B), so 1 IC chip can control 3 SMD5050 RGB lamps, and each lamp is individually controllable. This type stripe support both DC5v and 12V.

TM1809 Advantages
- Up to 24V, allowing for very long cable lengths
- Drives 3 pixels off a single SOP14 chip.
TM1809 Disadvantages
- Low PWM rate makes theses pixels unsuitable for cameras
- Data-only restricts refresh rates to be limited by the speed of the protocol, which will generally be slow
- Only 8 bits of data for each color makes dimming curves less smooth
- No redundancy in data
