Future Electronics Promotes the PCA9955A 16-Channel Constant Current LED Driver from NXP

Future Electronics promotes NXP's PCA9955A I2C-bus controlled 16-channel constant current LED driver.

Pointe Claire, Canada, March 13, 2015 --( Future Electronics, a global leading distributor of electronic components, promotes NXP's PCA9955A I2C-bus controlled 16-channel constant current LED driver.

The PCA9955A is an 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 LED output has its own 8-bit resolution (256 steps) fixed frequency individual PWM controller that operates at 31.25 kHz with a duty cycle that is adjustable from 0 % to 100 % 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 122 Hz and an adjustable frequency between 15 Hz to once every 16.8 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.

Each LED output can be off, on (no PWM control), set at its individual PWM controller value or at both individual and group PWM controller values. The PCA9955A operates with a supply voltage range of 3 V to 5.5 V and the constant current sink LED outputs allow up to 20 V for the LED supply.

This device has built-in open, short load and over-temperature detection circuitry. The error information from the corresponding register can be read via the I2C-bus. Additionally, a thermal shutdown feature protects the device when internal junction temperature exceeds the limit allowed for the process.
