24-channel Fm+ I²C-bus 57 mA/20 V constant current LED driver

The PCA9956B is an I²C-bus controlled 24-channel constant current LED driveroptimized for dimming and blinking 57 mA Red/Green/Blue/Amber (RGBA) LEDs in amusementproducts. Each LED output has its own 8-bit resolution (256 steps) fixed frequencyindividual PWM controller that operates at 31.25 kHz wit • 24 LED drivers. Each output programmable at: • Off\n• On\n• Programmable LED brightness\n• Programmable group dimming/blinking mixed with individual LED brightness\n• Programmable LED output delay to reduce EMI and surge currents\n• 24 constant current output channels can sink up to 57 mA, tolerat;
