PCA9626 Datasheet Led Driver

Manufacturer: NXP Semiconductors

Overview: PCA9626 24-bit Fm+ I2C-bus 100 mA 40 V LED driver Rev. 5 — 19 June 2014 Product data sheet 1.

General Description

The PCA9626 is an I2C-bus controlled 24-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.

An additional 8-bit resolution (256 steps) group PWM controller has both a fixed frequency of 190 Hz and an adjustable frequency between 24 Hz to once every 10.73 seconds with a duty cycle that is adjustable from 0 % to 99.6 % that is used to either dim or blink all LEDs with the same value.

Key Features

  • 24 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 brightnes.
