$Features & Applications

The PCA9685 is an I2C-bus controlled 16-channel LED controller optimized for LCD Red/Green/Blue/Amber (RGBA) color backlighting applications. Each LED output has its own 12-bit resolution (4096 steps) fixed frequency individual PWM controller that operates at a programmable frequency from a typical of 40 Hz to 1000 Hz with a duty cycle that is adjustable from 0 % to 100 % to allow the LED to be set to a specific brightness value. All outputs are set to the same PWM frequency.

Features and benefits:

  • 25 MHz typical internal oscillator requires no external components
  • External 50 MHz (max.) clock input
  • Internal power-on reset
  • Noise filter on SDA/SCL inputs
  • Edge rate control on outputs
  • No output glitches on power-up
  • Supports hot insertion
  • Low standby current
  • Operating power supply voltage range of 2.3 V to 5.5 V
  • 5.5 V tolerant inputs
  • −40 °C to +85 °C operation

Applications:

  • RGB or RGBA LED drivers
  • LED status information
  • LED displays
  • LCD backlights
  • Keypad backlights for cellular phones or handheld devices
