DM163 DM163 8x3-CHANNEL CONSTANT CURRENT LED DRIVERS General Description The DM163 is a LED driver that comprises shift registers, data latches, 8x3-channel constant current circuitry with current value set by 3 external resistors, and 64 x 256 gray level PWM (Pulse Width Modulation) function unit. Each channel provides a maximum current of 60 mA. The grayscale data are separated into BANK0 and BANK1 respectively, selected by SELBK pin. BANK0 is 6-bits grayscale data and the BNAK1 is 8-bits grayscale data. Depending on the system requirement, both PWM banks could be utilized jointly to achieve maximum 8+6 bit grayscale performance. Alternatively, users can choose either 64-graylevel bank or 256-graylevel bank for dot correction, and the remaining bank as image data. DM163 could also be constructed as a PWM controller for LED drivers. When VDDH is connected to VDD, each of the 24 output
