TLC5971: Find driver IC

Hi Gareth,

Sorry. I am currently out of office. I will reply to you by the end of 12/30/2022.

Hi Gareth,

Sorry for the delayed response.

• Could you please tell me what is the "penetrating screen" and what layout difficulty are customer facing?
• Could you please specify what is "resuming transmission from breakpoints"?

I need more detailed information to make a better suggestion for you.

BR,

Steven

Hi Steven

Thank you for your support

1. The width of the board is only 5mm, and the LED and Driver IC should be placed

2. Because the signals are connected in series, when a certain LED dies, the other LEDs do not need to be lit.

Hi Gareth,

You can take a look at TLC5948A, which has rather full failure diagnostic features.

Hi Steven

Customer feedback is too large to accommodate

Hi Gareth,

Is QFN package a must? Does the customer have any concern about the data communication lines?

Hi Steven

Can also be 3ch 25mA per channel But need 16bit

Hi Gareth,

TLC5943 has the VQFN package and supports 16-bit PWM.

BR,

Steven
