  • NXP Semiconductor PCA9922 8-Channel, Constant-Current LED Driver IC (Mouser) -- I'm loving this IC for my projects (as one who likes to bitbang jeir own PWM controls because I'm that cheap) because it can drive 8 LED's at a common constant current of 15mA to 60mA set with a single resistor, I can use separate LED and logic supplies, and it even supports short/open detection (although I have yet to use it).
