LPD-8803/8806 Datasheet
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 multi-
gray full-color lighting system.
Features
1. Constant current driving mode, the default driving current is 18mA, supporting
LED lighting voltage up to 12V.
2. LPD8803 support three-way output (pin downward compatible with LPD6803), LPD8806
support the six outputs (pin arrangement conducive to single-panel layout).
3. Two-wire control mode, the shift clock up to 20MHz.
4. Unique data clock regeneration mechanism, super signal drive capability, support
cascading length over 2000 pixels.
5. Built-in 1.2M oscillation circuit, support FREE-RUN mode, easy to programable design
(refresh rate greater than 4000Hz).
6. Built-in 256 independent PWM grayscale control circuit for each channel, 1024
grayscale effect can be achieved by programming.
7. The seven output polarity is Optional ,support an external drive or as a source of
high-power LED driver circuit.
8. Industrial-grade design, input signal processing Schmidt,
strong anti-interference performance.
Applications
1. LED decorative lighting system
2. PWM signal generator
3. LCD backlight driver

Plug-in constant current drive mode:
The mode (OMODE = HIGH level or floating) appliable when each single string has
multiple LEDs and the VDD exceeds 12V.
It is using the external NPN triodes to improve the drive voltage capability, at the same
time, make all the device characteristics maintain the constant current drive: ILED = 18mA.
The maximum VDD's withstand voltage is depended on the NPN triodes' VCEO, as usual,
more than 25V.
Cascade signal's driving and connecting:
Considering the cascade transmission distance may be very long among the chips, the
output ends of the SDO and SCLKO are designed with strong push-pull type drive circuits,
Tests show that when the CLOCK is 2M, it can drive up to 6M signal line. To avoid the
signal reflection, pls series connect a about 33ohms resistor at both ends of SDO and
SCLKO, and then output to the next level during your application
