A6282 - 16-Channel Constant-Current LED Driver

General Description

TheA6282 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.

Key Features

  • 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 Packages: 24-pin T.
