Hi Nathan Kando,
Nathan Kando said: Are T.high.min and T.low.min static values for all T.cycle, or are they dynamically dependent on T.cycle (without this being indicated in the datasheet)?
the T.high.min and T.low.min are same for all T.cycle which i…
Part Number: TLC6983 When a short occurs for each color in a product designed with 30 SCAN, 30 LEDs light up like GREEN + BLUE. In this case, it is difficult to find which LED has the short circuit. I am looking for defects by removing the LEDs one by one…

How is V.knee defined?
In the data sheet, the maximum knee voltage is reported as:
V.knee.max @ V.cc = 2.8 [V] @ I.channel = 10 [mA] = 0.30 [V] …

Part Number: TLC6983 I'm using TLC6983 for 1mm pitch LED panel.
And only use 11-bit PWM for display because I need a very fase frame rate. (about 2000Hz).
I can't remove the first scan line dim & gradient dim with changing register FC4 [35:38].…
Hi Nick,
thanks for your suggestion. this is the most complex device in our product line and includes lots of unique features. considering the competitor, we don't public all information in the official website. which part make you feel confused and we…
Part Number: TLC6983 Hello,
We are using one TLC6896 to drive a 48x16 monocolor red led matrix. In our schematic we use 6.8k for Rref. We want to achieve 20 mA output current. I am attaching our list of parameters that we are currently using. The problem…
Part Number: TLC6983 In the document, the below comments are a little confusing so I want to be sure,
" lines are not used in each matrix, and these unused pins can be floated.
For the software, TI suggest zero data to send to the unused channels. There…
