TLS3001 Pixel Protocol
The TLS3001 is a single-wire addressable RGB LED driver with 12-bit per-channel PWM and a wide 5 to 17V pixel supply range.

Strengths
- 12-bit per-channel PWM (4096 levels per colour) gives finer gradients and smoother low-end dimming than typical 8-bit single-wire chips.
- The SOP14 package provides a redundant data line, so a single failed pixel need not break the rest of the chain.
- Single-wire, data-only wiring keeps installation simple: one data conductor plus power, with no separate clock line to route or terminate.
Limitations
- As a data-only, self-clocking protocol it is timing-sensitive: long inter-pixel runs, marginal cabling, or poor level-shifting can corrupt the signal, and the redundant data line is only available on the SOP14 package (not SOP8 or SOP10).
- 1000Hz PWM is comfortably flicker-free at up to 34fps but leaves limited margin for higher-frame-rate or slow-motion capture, and the part is RGB only, with no dedicated white (RGBW) channel.
Overview
The TLS3001 is a single-wire, individually addressable RGB LED driver: data travels on one self-clocking line, so timing tolerances matter and inter-pixel runs should be kept sensible. Each pixel integrates a controller delivering 12-bit per-channel PWM (4096 levels per colour) for smooth gradients and clean low-end dimming, operates across a 5 to 17V supply, and on the SOP14 package adds a redundant data line for chain resilience. Its 1000Hz refresh is comfortably flicker-free for camera work up to 34fps. ENTTEC pixel controllers (OCTO 71521, PIXELATOR MINI and MK2 70067/70068, DIN PIXIE 73539, and PLINK Injectors) drive a wide range of pixel protocols; contact ENTTEC about chips not listed.

ENTTEC has been engineering lighting control in Australia since 1999, and shipping LED pixel controllers since the original Pixelator in 2014.
