TLC5926-Q1: Value of output current in chapter 10.1.2

Bertram

Part Number: TLC5926-Q1

Tool/software:

In the datasheet of TLC5926-Q1 chapter 10.1.2 (Adjusting Output Current) is a calculation for the Output-Current (5). e.g. 26 mA at 720 Ohm. In Figure 16 the output current at 720 Ohm is approximately 40 mA. What value is currect, 26 mA or 40 mA?

Hi Bertram,

What do you mean that the current is 40mA in Figure 16. I saw it's a Current Gain vs Configuration Code figure. Can you describe it more detailedly.

Best Regards,

Suchen

Do we have the same datasheet?

Hi Bertram,

Just noticed that the datasheet of TLC5926-Q1 has a wrong curve. Please refer to the Figure 15 of the non-auto version datasheet TLC5926 data sheet, product information and support | TI.com for the correct curve. Or use the equation to calculate the current directly. Thanks!

Best Regards,

Suchen
