Part Number: TLC5944
Hi, I'd like some input on how to read the supply current specs for the TLC5944 led driver.
Kenneth Du replied (in now locked thread):
Icc3/Icc4 is with LEDs all on of full greyscale while Icc1/Icc2 is without any LED's ON since BLANK is high.Rief changes the Reference Current in IC and will cause Typ/Max's cahnge. You can refer to the function block diagram.
- Icc3/Icc4, please clarify why the numbers are different as only the Riref resistor has changed (the numbers in the table I assume excludes the actual LED's)
- If we lower DCn (dot correction current register) to say half of the configured Riref, will this also lower the current consumption of the led-driver itself?
- As Icc1/Icc2 will show an increase in quiescent current when led's are off (blank is high), is there a way to reduce the quiescent purely in software? (i.e. I don't want to switch the supply off, nor trying to actively increase the resistance of Riref)
