A6282: 16-Channel Constant-Current LED Driver

Discontinued
This part is discontinued. Samples are no longer available.
Date of status change: May 6, 2016.
Recommended Substitutions: For existing customer transition, and for new customers or new applications, contact Allegro Sales.

The A6282 device is designed for LED display applications. This 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 two 24-terminal packages: QFN (package ES) and TSSOP (LP), which have an exposed thermal pad. Both packages are lead (Pb) free with 100% matte tin leadframe plating.

Applications

Monocolor, multicolor, or full-color LED display
Monocolor, multicolor, or full-color LED signboard
Display backlighting
Multicolor LED lighting
