PCA9958 Datasheet (NXP) - 24-channel SPI serial bus 63mA/5.5V constant current LED driver

PCA9958, 24-channel SPI serial bus 63mA/5.5V constant current LED driver

PCA9958 is a daisy-chain SPI-compatible 4-wire serial bus controlled 24-channel constant current LED driver optimized for dimming and blinking 63 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 3

PCA9958 Features

* 24 LED drivers. Each output programmable at:

* Off

* On

* 8 bits programmable LED brightness

* 8 bits programmable group dimming/blinking mixed with individual LED brightness

* Programmable LED output delay to reduce EMI and surge currents
