Greetings,
Can I connect my LED directly to OUTx without a series resistor?
I want to connect several LEDs (2 x 7 segment - 14 LEDs) to a TLC59282. The LEDs have a voltage drop of about 1.8V when I use 5-10mA of current. The supply voltage for the LEDs is will vary from 3 volts to about 4.6 volts. I have done my worst case thermal calculation and I don't believe I will have any problems.
What is not entirely clear to me is if I can connect each LED to a OUTx pin without a series resistor. If I read the data sheet correctly I can connect the LED directly to the OUTx pin, program the sink current (my case 5mA) with IREF, and the voltage drop across the TLC59282 will be Vsupply - Vdiode (4.6V - 1.8V = 2.8V) and the power contribution from that pin is 2.8V*5mA = 14mW.
I wanted to know if I am understanding the data sheet correctly.
Thank you,
Frank
