TM1914 IC for rgbww 5in1 pixel led tapes addressable Chip Components
stars, based on 0reviews
This pixel protocol was designed by Titan Micro Electronics in China. It is an improved design of its previous version, TM1804, but offers a redundant data line to allow a continuous data path even if a single pixel fails. The control circuit comes in a SOP8 package, allowing for more flexibility with LED choice, normally used for RGBWW/RGBCCT pixel led strip.

TM1914 Advantages
- Up to 24V, allowing for very long cable lengths
- Redundant data line reduces chance of entire strip failure
TM1914 Disadvantages
- Data-only restricts refresh rates to be limited by the speed of the protocol, which will generally be slow
- Low PWM rate only allows for filming these pixels with cameras up to 23fps
- Only 8 bits of data for each color makes dimming curves less smooth
