Key Features

  • Active LOW Output Enable (OE) input pin for hardware blinking and dimming of LEDs.
  • Hardware and software programmable I²C-bus addresses, allowing multiple devices to be connected to the same bus.
  • Software Reset feature (SWRST Call) for resetting the device through the I²C-bus.
  • No glitch on power-up and supports hot insertion.
  • Low standby current and edge rate control on outputs.
  • INVRT and OUTDRV bits in the MODE2 register for controlling external drivers and LED output polarity.

Applications

  • RGBA color mixing applications such as LED lighting systems, display backlighting, and ambient lighting.
  • Automotive lighting systems where precise color control is necessary.
  • Industrial and consumer electronics requiring advanced LED control.
  • Signage and display systems that need dynamic color adjustment.
