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, and amber (RGBA) LEDs. Each LED output offers a 6-bit resolution (64 steps) preset current configuration with an absolute accuracy of ±8%. The PCA9959 operates with a supply voltage range of 2.7V to 5.5V and includes an open short-load and overtemperature detection circuitry. The driver uses a four-wire read/write serial bus with a higher data clock frequency of up to 10MHz. Applications include RGBA LED drivers, LED status information, IR coding communication, LCD backlights, and keypad backlights for cell phones. NXP Semiconductors PCA9959 LED Lighting Driver is offered in a compact 5mm x 5mm x 0.85mm HVQFN40 package, with a -40°C to +85°C operating temperature range.
