PCA9624PW - LED driver

Download the PCA9624PW datasheet PDF. This datasheet also covers the PCA9624 variant, as both devices belong to the same led driver family and are provided as variant models within a single manufacturer datasheet.

Description

The PCA9624 is an I2C-bus controlled 8-bit LED driver optimized for voltage switch dimming and blinking 100 mA Red/Green/Blue/Amber (RGBA) LEDs.

Features

  • 8 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.

PCA9624 8-bit Fm+ I2C-bus 100 mA 40 V LED driver Rev. 4.1 — 18 January 2016 Product data sheet 1. General description The PCA9624 is an I2C-bus controlled 8-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.
