PCA9955, PCA9952 Datasheet - NXP

PCA9955 16-channel constant current LED driver

The PCA9952 and PCA9955 are I2C-bus controlled 16-channel constant current LED driver optimized for dimming and blinking 57 mA Red/Green/Blue/Amber (RGBA) LEDs in amusement products. Each LEDn output has its own 8-bit resolution (256 steps) fixed frequency individual PWM controller that operates at .

PCA9955 Features

* 16 LED drivers. Each output programmable at:

* Off

* On

* Programmable LED brightness

* Programmable group dimming/blinking mixed with individual LED brightness

* Programmable LEDn output enable delay to reduce EMI and surge currents

* 16 constant current output channel
