Hi, We are using LED driver (LED2472GBTR) in one of our products. Can we make RGB[1:8] outputs high (VDD=3.3V)? If so how? Regards, Veera

Welcome, @VAkul.1​, to the community!

Actually, you only need to switch / OE inactive to have all outputs also inactive. However, the outputs are not push-pull stages, but current sinks, the current of which can be set with a resistor connected to iset.

Are you aware that VDD is not limited to 3.3V, but can be between 3...5V?

What do you want to achieve by setting all outputs high?

Hi Peter,

Thank you for the Reply.

Actually we don't want to inactive all outputs. We want to control R[1:8], G[1:8] and B[1:8] outputs independently.

Can we control these Outputs independently low or high (particular segment LED on/off). If so how?

Regards,

Veera

Hi, Veera,

Of course, you can set all outputs independently of each other as you like. However, the LED2472G is controlled serially (works as a serial-parallel converter) and therefore the data of all 24 outputs have to be rewritten for every change of only one output, even if their level is unchanged.
