WS2818 IC 5V / 12V 60 LED Digital LED Strip Light , WS2818 Break - Point Transmission LED Strip
Feature :
1 . WS2818 is a 3-channel LED driver control circuit, its internal
include intelligent digital port data latch and signal reshaping
amplification drive circuit. Also include a precision internal
oscillator and a 12V voltage programmable constant current control
part, which achieves highly consistent color effect.
2. WS2818 has strong features in Signal Break-point Continuous
Transmission, it adopts dual signal transmission, these signals are
able to work together without interaction. The user can select the
first chip DIN/BIN as the control signal input pin, and the
follow-up cascade chips will automatically identify the output
signal released by the first chip which not to affect the whole
display effect.
3. WS2818 adopts Single-line Return-to-Zero communication protocol.
After the chip gets power-on reset, the DIN port receive data from
controller, the first chip collects initial 24bit data then sent to
the internal data latch, the other data which reshaping by the
internal signal reshaping amplification circuit sent to the next
cascade pixel through the DO port. The data reduced 24bit after
transmitted through every pixel. Since WS2818 adopts auto-reshaping
transmit technology, making the pixel cascade numbers are not
limited to the signal transmission, but to signal transmission
speed. When BIN works as control signal receiving interface, its
control data is 24bit more than the DIN interface, so as to ensure
that the two ways to control the number of pixels is the same
4. Based on the received 24bit data, the internal data latch
generates different duty cycle control signals in the OUTR, OUTG,
OUTB port. All chips synchronous send the received data to each
segment when the DIN port input a reset signal. It will receive new
data again After the reset signal finished. Before a new reset
signal received, the control signal of OUTR, OUTG, OUTB pin
unchanged. The chip exports PWM data to OUTR, OUTG, OUTB pins,
after receive a low voltage reset signal the time retain over
300us.
SOP8 and MSOP8 packaging available for sale.
WS2818 Break-point Transmission LED Strip Description :
1. 5V/12V available, that work on different applications of stable
pressure.
2. Built-in 12V voltage regulator tube, only add a resistance to IC
VDD pin when the voltage is below 12V.
3. Adopts the built-in signal reshaping circuit to achieve the
signal waveform shaping, and thus no signal waveform distortion
takes place.
4. Built-in power-on reset and brown-out reset circuits.
5. The gray levels of each pixel of 256 levels, and the refresh
frequency reaches to 2KHz/s.
6. Serial cascading interface, data receiving and decoding are all
achieved by one signal line.
7. Signal Break-point Continuous Transmission, any pixel’s failure, it
won’t affect the whole display effect.
8. The distance of any two signal transmission points is less than
5 meters, there’s no extra circuits needed.
9. When the refresh rate of 30fps, the cascade number are not less
than 1024 pixels.
10. Send data at speeds of 800Kbps.
11. Good consistency reliability, high cost-effective.
