A6285 - 16-Channel Constant-Current Latched LED Driver

General Description

The A6285 is designed for LED display applications.

This BiCMOS device includes an On/Off shift register, a Dot Correction (DC) shift register, accompanying data latches, and 16 MOS constant-current sink drivers with active pull-ups that can be enabled or disabled as required by the application.

Key Features

  • 3.0 to 5.5 V logic supply range.
  • Schmitt trigger inputs for improved noise immunity.
  • Power-On Reset (POR).
  • Up to 80 mA constant-current sinking outputs.
  • LED open circuit detection (LOD).
  • Dot correction (DC) for adjusting LED light intensity on each channel with 7-bit resolution.
  • Low-power CMOS logic and latches.
  • High data input rate up to 30 MHz.
  • Active output pull-ups with enable/disable.
  • 20 ns typical staggering delay between outputs.
  • Int.
