TLC5925: IO and VO Characteristics

Sho Ogane

Part Number: TLC5925

Hi all.

I have two questions.

1.How much is the maximum output cuttent at Vo>0.6V.
   Is it 45mA?

2.There is output current - output voltage graph in the datasheet.
   I attached the following,
   The temperature of this graph is 25℃
   I would like to know the output current - output voltage graph at 50℃
   Can I refer to the following graph when Ta= 50℃?

Best Regards,
Sho

Hi Sho,

Sorry for the late reply.

The max output current per channel is 45mA. You can connect multiple channels in parallel to increase this value. I would advise having at least 1V on the output pin of the TLC5925 in order to make sure you are in the flat region of the output current vs output voltage graph.

For the temperature dependence, you can use the same graph. We've confirmed this on similar IP.
