dm163 8x3信道4096級pwm驅(qū)動ic

dm163  8x3信道4096級pwm驅(qū)動IC  

        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 channels outputs can act as an inverse digital signal for controlling the led driver.

    features: 24 output channels;  8 + 6-bits pwm grayscale control; constant current output: 5ma to 60ma; led power supply voltage up to 17v;  vdd=3v to 5.5v ; varied output current level set by 3 external resistors;  serial shift-in architecture for grayscale data
