LED Driver with Dot Correction and Brightness Control at Affordable Price!
SiTI's DM164 is a PWM-controlled LED driver which features dot correction and global brightness control...
The DM164 is a LED current sink driver incorporating independent shift registers and data latches for grayscale PWM data (GM mode) and current adjustment data (D&G mode). This feature-rich device is priced to allow for rapid penetration into high-volume applications such as video walls and electronic scoreboards.
Features include 8x3 channels constant current circuitry with current value set by 3 external resistors, a 65,536 grayscale PWM function unit, 128 levels of current adjustment for each channel and 256 levels of global brightness control (white balance). Each channel provides a maximum current of 90mA.
The DM164 also supports LED open detection capability, thermal alarm and shutdown functions. There are two methods to communicate error signals to the system: one is through serial output data to indicate which channel has failed; the other is by means of a dedicated alarm pin.
The DM164 in available in LQFP48 and QFN48 packages.
