What is LPD8806 addressable LED strip light?
LPD8806 LED supports DC5V low voltage input, a single IC controls 2 LEDs, 2LEDs cuttable, high scanning frequency (>4000HZ), 8806 is a new generation driver chip designed for LED lighting systems, it uses advanced industrial-grade CMOS technology (NMOS The integrated circuit made by the device and the PMOS device) provides multiple constant current drives and grayscale modulation output, which is especially suitable for discrete multi-grayscale full-colour lighting systems.
Unique data clock regeneration mechanism, super signal drive capability, support cascade length over 2000 points; built-in 1.2M oscillator circuit, support FREE-RUN mode, easy to program and design the controller; each channel is built-in independent 256-level PWM The gray-scale control circuit can achieve 1024-level gray-scale effect through programming.
The LPD chip includes a serial shift register and a cascade drive circuit. The gray data is shifted into the serial shift register on the upper edge of the clock, after dumping, it is converted to a multi-port parallel output by pulse width modulation. The serial shift register and the gray and the degree counter can be controlled by different clock signals,while the data and control signals are output to the next level circuit after a strong internal drive.
