WS2811 WS2811S Constant current LED drive IC
Rp2.500
PLEASE READ DATASHEET FIRST , Before use.
(Wajib Baca Datasheet).
Kesalahan pemasangan/penyolderan bukan tanggung jawab kami. terima kasih.
The WS2811 is 3 output channels special for LED driver circuit. It 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 output drive. In the purpose of reduce power supply ripple, the 3 output
channels designed to delay turn-on function.
IC use single NZR communication mode.After the chip power-on reset, the DIN port receivedata from con
troller, the first IC collect initial 24bit data then sent to the internal data latch, theother data which reshaping
by the internal signal reshaping amplification circuit sent to the next cascade IC through the DO port. After
transmission for each chip,the signal to reduce 24bit. IC adopt auto reshaping transmit technology, making the
chip cascade number is not limited the signal transmission, only depend on the speed of signal transmission.
The data latch of IC depend on the received 24bit data produce different duty ratio signal at OUTR,
OUTG, OUTB port. All chip 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 port unchanged. IC sent PWM data that received justly to OUTR,
OUTG, OUTB port, after receive a low voltage reset signal the time retain over 50us. We offer two package
SOP8 and DIP8.
Applications :
# LED decorative lighting.
# Indoor/outdoor LED video or irregular screen.
