NXP PCA9624PW,112

线性2.3V5.5V100mA

Overview

The PCA9624PW,112 is an I²C-bus controlled 8-bit LED driver optimized for voltage switchdimming and blinking 100 mA Red/Green/Blue/Amber (RGBA) LEDs. Each LED outputhas its own 8-bit resolution (256 steps) fixed frequency individual PWM controller thatoperates at 97 kHz with a duty cycle that is adjustable from 0 % to 99.6 % to allow theLED 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 frequencybetween 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.

The PCA9624PW,112 and PCA9634 software are identical and if the PCA9624PW,112 on-chip 100 mANAND FETs do not provide enough current or voltage to drive the LEDs, then thePCA9634 with larger current or higher voltage external drivers can be used.
