A6282  
16-Channel Constant-Current LEDDriver  
Features and Benefits  
Description  
TheA6282deviceisdesignedforLEDdisplayapplications.This  
16 constant-current outputs, up to 50 mA each  
LED output voltage up to 12 V  
3.0 to 5.5 V logic supply range  
Schmitt trigger inputs for improved noise  
immunity  
Power-On Reset (POR), all register bits = 0  
Low-power CMOS logic and latches  
High data input rate: 30 MHz  
Output current accuracy: between channels  
<±3% and between ICs ±7%, over the full  
operating temperature range  
Internal UVLO and thermal shutdown (TSD)  
circuitry  
CMOS device includes an input shift register, accompanying  
data latches, and 16 MOS constant current sink drivers.  
The CMOS shift registers and latches allow direct interfacing  
with microprocessor-based systems. With a 3.3 or 5 V logic  
supply, typical serial data input rates can reach up to 30 MHz.  
The LED drive current level can be set by a single external  
resistor, selected by the application designer. A serial data  
output permits cascading of multiple devices in applications  
requiring additional drive lines.  
The A6282 is available in a variety of 24-terminal packages:  
QFN (package ES) and eTSSOP (LP), which have an exposed  
thermal pad, and SOIC (LW). All packages are lead (Pb) free  
with 100% matte tin leadframe plating.  
Applications include the following:  
Monocolor, multicolor, or full-color LED display  
Monocolor, multicolor, or full-color LED signboard  
Display backlighting  
Packages:  
24-contact QFN  
4 mm × 4 mm × 0.75 mm
