8.4.1 Maximum Current Control (MC) Function

The maximum output current per channel, IOLCMax, is programmed by the MC data and is set with the serial interface. IOLCMax is the largest current for each output. Each OUTXn sinks the IOLCMax current when they turn on and the dot correction and global brightness control data are set to the maximum value of 7Fh (127d).

When the device is powered on, the MC data are set to 0. MC data should be changed when all constant-current outputs (OUTXn, where X = R, G, or B; n = 0 to 7) are off. MCX = 6 and MCX = 7 are used when VCC is greater than 3.6 V. The same MC data must be written twice to change the maximum constant-current output. Table 8-8 shows the characteristics of the constant-current sink versus the maximum current (MC) control data.
