Preliminary
The second method is using generic cut-off control IC.
In second method, you must use pull-up resistor.
Case 1. 5V Pull-up
In above picture, RCT pins outputs 5V - (From 0 to 500uA ) x 10K = from 5V to 0.3V DC level.
So, all kinds of cut-off IC using 0 - 5V input range can be used.
cut-off Register : 00H
5V
FFH
5V - 10K x 500uA = 0.3V
cut-off Brightness Register : 00H
5V
FFH
5V - 10K x 200uA = 3V
When using 10k pull-up resistor, you can get the 5V output range.
But, the 5V range include cut-off bright range. So, if you set 1V bright range, you must consider 1.3 - 5V cut-off
range for white balance.
