A6281 - 3-Channel Constant Current LED Driver

General Description

The A6281 is a 3-channel constant current LED driver that has a wide range of output currents.

The A6281 controls LED brightness with a Pulse Width Modulation (PWM) scheme that gives the application the capability of displaying a billion colors in an RGB cluster.

Key Features

  • 3 × 10-bit PWM brightness settings 3 × 7-bit dot correction current settings 5 to 17 V operation Wide output current range, 10 to 150 mA per channel Internally generated PWM clock Serial port operates at up to 5 MHz Data and clock logic architecture allows single www. DataSheet4U. com microcontroller control of large quantities of seriallyconnected A6281s at fast data transfer rate.
  • Buffered logic outputs to drive cables.
  • Thermal shutdown and UVLO protection.
  • Power-On Reset.
