LPD-8803

- 8803/8806 Datasheet LPD LPD- LPD8803/LPD8806 as a new generation of driver chips are designed for the LED lighting system, which uses industrial grade CMOS process, providing multi-channel constant current driver and grayscale modulation output, it is programable, LPD8803 and LPD8806 output 3chanhel and 6 channel respectively,signal particularly suitable for discrete multigray full-color lighting system. 1. Constant current driving mode, the default driving current is 18mA, supporting LED lighting voltage up to 12V. 4. Unique data clock regeneration mechanism, super signal drive capability, support cascading length over 2000 pixels. 7. The seven output polarity is Optional ,support an external drive or as a source of high-power LED driver circuit. Applications 2. PWM signal generator 3. LCD backlight driver Pin Figure Gr ee LPD8803 1. LED decorative lighting system led 8. Industrial-grade design, input signal processing Schmidt, strong anti-interference performance. Ele 6. Built-in 256 independent PWM grayscale control circuit for each channel, 1024 grayscale effect can be achieved by programming. ctr 5.
