8 pin led driver

 · The ULNA has 8 separate drive channels each comprised of high current NPN Darlington transistor pairs with built-in kick-back diodes for switching inductive loads like motors. The internal logic for each channel is shown to the right. Using the fact that many microcontroller pins have three states (+V, GND, or. "high impedence", you can drive N* (N-1) LEDs from N pins. So the little 8. pin microcontroller like a PIC12Fxxx or an ATtiny11 can drive 20 LEDs on. its five available output pins, and still have one pin left for some kind of input. Integration Minimizes BOM for High-Brightness LED Driver, Saving Space and Reducing Cost. Wide Input-Voltage Range from 5V to 60V ; H-Bridge Single Inductor Buck-Boost Architecture ; Constant-Current and Constant-Voltage Regulation ; pin TSSOP with EP Pad and pin(5mm x 5mm) TQFN with EP Pad Packages; Wide Dimming Ratio allows High.
