PCA9625 Datasheet 16-bit Fm I2c-bus 100 Ma 24v Led Driver

Manufacturer: NXP Semiconductors

Overview: PCA9625 16-bit Fm+ I2C-bus 100 mA 24 V LED driver Rev. 02 — 15 January 2008 Product data sheet 1.

General Description

The PCA9625 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.

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

  • I 16 LED drivers. Each output programmable at: N Off N On N Programmable LED brightness N Programmable group dimming/blinking mixed with individual LED brightness I 1 MHz Fast-mode Plus compatible I2C-bus interface with 30 mA high drive capability on SDA output for driving high capacitive buses I 256-step (8-bit) linear programmable brightness per LED output varying from fully off (default) to maximum brightness using a 97 kHz PWM signal I 256-step group brightness control allows general dimming.
