$Features & Applications

The PCA9635PW/Q900,118 is an I2C-bus controlled 16-bit LED driver optimized for Red/Green/Blue/Amber (RGBA) color mixing applications. Each LED output has its own 8-bit resolution (256 steps) fixed frequency individual PWM controller that operates at 97 kHz with a duty cycle that is adjustable from 0 % to 99.6 % to allow the LED to be set to a specific brightness value.

It is one of the first LED controller devices in a new Fast-mode Plus (Fm+) family. Fm+ devices offer higher frequency (up to 1 MHz) and more densely populated bus operation (up to 4000 pF) 


  • 16 LED drivers. Each output programmable at:
    • Off
    • On
    • Programmable LED brightness
    • Programmable group dimming/blinking mixed with individual LED brightness
  • 7 hardware address pins allow 126 devices to be connected to the same I2C-bus
  • Software Reset feature (SWRST Call) allows the device to be reset through the I2C-bus
  • 25 MHz internal oscillator requires no external components
  • Internal power-on reset
  • Noise filter on SDA/SCL inputs
  • Edge rate control on outputs
  • No glitch 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


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