$Features & Applications

The PCA9622DR,118 is an I²C-bus controlled 16-bit LED driver optimized for voltage switch dimming and blinking 100 mA Red/Green/Blue/Amber (RGBA) LEDs. 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.

The PCA9622 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). If the PCA9622 on-chip 100 mA NAND FETs do not provide enough current or voltage to drive the LEDs, then the PCA9635 with larger current or higher voltage external drivers can be used.

Features:

  • 16 LED drivers. Each output programmable at:
    • Off
    • On
    • Programmable LED brightness
    • Programmable group dimming/blinking mixed with individual LED brightness
  • 1 MHz Fast-mode Plus compatible I²C-bus interface with 30 mA high drive capability on SDA output for driving high capacitive buses
  • 256-step (8-bit) linear programmable brightness per LED output varying from fully off (default) to maximum brightness using a 97 kHz PWM signal
  • 256-step group brightness control allows general dimming (using a 190 Hz PWM signal) from fully off to maximum brightness (default)
  • 256-step group blinking with frequency programmable from 24 Hz to 10.73 s and duty cycle from 0 % to 99.6 %
  • Sixteen open-drain outputs can sink between 0 mA to 100 mA and are tolerant to a maximum off state voltage of 40 V. No input function
  • 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
  • No glitch on power-up
  • Supports hot insertion
  • Low standby current
  • Operating power supply voltage (VDD) range of 2.3 V to 5.5 V
  • 5.5 V tolerant inputs on non-LED pins
  • -40 °C to +85 °C operation
  • Package offered: TSSOP32

Applications:

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