LM36923H: Using 2 strings with the LM36923H

Hello team,

In my application I don’t need the 3^rd string of the LM36923H.

Can you help with the questions below?

• I do not intend to use the PWM input, only the I2C. Therefore, the question is do I leave pin unconnected or should pull high or low?
• When using the LM36923H, the 3^rd string input LED3, which will not be used, do we leave just unconnected or should it be pulled high or low?

Thanks!

Connor
