SM16704 - Signal line 256 Gray level 4 channel Constant current LED driver IC
The SM16704 is 4 output channels control IC that special for LED driver circuit.Its internal includes power clamp module, signal decoding module Block, oscillation module, data regeneration module, output current drive module, etc.
The SM16704 IC use single ZR communication mode and adopt auto reshaping transmit technology,ensuring that the data is not fading during serial transmission.the DIN port receive data from controller, the first IC collect initial 32bit 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 IC through the DO port.
