PCA9959 LED Lighting Driver

NXP Semiconductors PCA9959 LED Lighting Driver is a daisy-chain SPI-compatible 4-wire serial bus controlled 24-channel constant preset current LED driver. This driver is optimized for dimming and blinking 63mA Red/Green/Blue/Amber (RGBA) LEDs. Each LED output offers a 6-bit resolution (64 steps) preset current configuration with an absolute accuracy of ±8%. The PCA9959 driver operates with a supply voltage range of 2.7V to 5.5V and includes a built-in open short load and over-temperature detection circuitry. The PCA9959 LED lighting driver is designed to use a 4-wire read/write serial bus with a higher data clock frequency up to 10MHz. Typical applications include RGBA LED drivers, LED status information, IR coding communication, LED displays, LCD backlights, and keypad backlights for cellular phones.
