    12 V Programmable IC Chips , Constant Current LED Driver IC WS2811 For LED Lights

    WS2811 Programmable Constant Current LED Drive IC


    General Description:
    WS2811 is three-channel LED drive control a dedicated circuit, chip internal contains intelligent digital interface data latch signal plastic amplifier drive circuit, Also contains a high accuracy of internal oscillator and 15 V high-pressure programmable rated current output drive. At the same time, in order to reduce power supply ripple, 3 channels have certain
    The delay of the conduction function, so that in the frame refresh, can reduce circuit ripple. Chip adopt wired to zero yards of communication, chip in the electric reset after, DIN end accept Mosaic of data from the controller, send over the first 24 bit data is the first chip after extraction, sent to chip internal data latches, the rest of the data by internal plastic processing circuit plastic amplification
    Through the DO port forwarding output to start a cascade of chip, each after a chip transmission, signal reduce 24 bit. Chip adopt automatic plastic
    Forwarding technology, makes the chip of the cascade number from signals the limit, only limited signal transmission speed requirements.
    Chip internal data latches according to accept to 24 bit data, in OUTR, OUTG, OUTB control terminals produce different than control of empty letter
    Th, waiting for the input signal RESET DIN, all chip synchronous will receive the data sent to each section, chip in the signal to pick up after
    By new data, in the start of the 24 bit received the data, through DO mouth forward data mouth, chip in didn't accept to RESET before yards, OUTR,
    OUTG, OUTB tube foot the original output remains the same, when accept to 50 μ s low level above RESET to code, chips will just received 24 bit PWM
    Data output pulse width to OUTR, OUTG, OUTB pin. Provide SOP8 and DIP8 two kinds of packaging.



    Features:
    The main features
    Output port compression 12 V.
    Chip built-in voltage stabilizing tube, 24 V the following the power of resistance to only IC VDD feet, no plus voltage stabilizing tube.
