Pixel IC · Full-Pixel Series
Every bead gets its own address, with live (on-line) and pre-stored (off-line) data — full-gamut control across points, lines, planes and 3D.
Third-generation anti-interference architecture: fuse-region surge protection and interference-resistant decoding. 256+ beads per channel, working at both high-voltage AC 110/220V and low-voltage DC — our current workhorse part.
Four-channel output; an independent white channel lets warm-white scenes and full-color motion coexist, meeting the color-quality demands of premium retail and professional installations.
Purpose-built for copper-wire and PVC-wire lights. The P9871's two-layer address (18-bit laser fuse + 8-bit poly fuse) lets a single feed reel complete both assembly and addressing on an automated SMD line; the parallel structure supports automatic detection of faulty beads and re-addressing after replacement.
Patented two-section address design (10 bits split into 6+4), so one chip recognizes two sets of information at once. Laser-trim grading of functions — synchronized/random blink, 1–32 fixed codes, and fixed-plus-random sectioned combinations — covers high-volume full-color tree lights across price points.
A new high-speed carrier protocol (core patent US 11,152,972 B1) that raises refresh rate and LED count on the same two wires and decodes reliably even with voltage drop at the far end of long strings.
Single-level power-line carrier: the supply line is pulled straight to 0 V to send data while built-in charge storage keeps the chip running — so the controller needs just one MOSFET. 256-step PWM, field-burnable 8-bit address, RGBW zone compensation and a Low Vds design save power in series strings; P9165AH/A add 8-step current gain for battery and solar strings. Bead operating current is about 70% below the benchmark part.
Built for year-round eave lighting: five constant-current outputs R/G/B/CW/WW (up to 60 mA each), with independent cool- and warm-white channels for direct color-temperature control; 16-bit grayscale (65,536 steps) and 25 kHz PWM — no flicker on phone video. VDD 4.5–38V for long 36V runs; sleep current <100 µA when off with no data. Single-wire RZ cascade protocol.
Two-wire power-line carrier with four constant-current R/G/B/W outputs (up to 19.5 mA each, 256-step PWM) for standard two-pin bases such as E27 / GU10 / MR16. Each chip ships with a laser-trimmed 24-bit unique address, so users replace failed bulbs themselves — the controller detects the new bulb by its power draw and learns its address automatically (US 12,452,984), no addressing tool needed.

P9165 Series · Constant-Current Carrier
Data rides on the power line as pull-low pulses, so two wires carry both power and control. Field-programmable addresses, 256-level PWM grayscale and constant-current drive; four parts cover high-speed RGB, rectified-AC high voltage, bulbs and low-voltage DC strings.

PLC Carriers
A PLC carrier uses a modulation circuit to merge power and control signal onto one pair of wires: plug an existing SPI or DMX512 controller into a carrier and it drives two-wire pixel strings directly.
A modulation circuit merges power with the controller signal and outputs a carrier signal; two wires (+/−) go to the string with no separate signal line.
The signal side maps to 8 controller ports; outputs 1–8 each provide a two-wire carrier output for one controller port.
Merges power with a DMX512 signal into a carrier the beads understand; two wires to the string, connecting straight into stage and project control systems.
Multiple outputs extend how many beads each controller port can drive — one set of lights per output — cutting controller cost on projects.
A two-in-one controller for two-wire parallel beads: no separate programmer needed — beads are addressed one by one in-line as bulbs are installed, and effects play right away. Supports the 9874A, 9873A and similar.
