The XRP7620 is a multi purpose 4-channel independently adjustable current sink driver. Optimized for LED backlighting and RGBW/RGBA color mixing applications, the XRP7620 can also be used as a generic software programmable current sink I/O expander.
Supporting an industry standard 2-line I²C serial interface, the XRP7620 provides full independent control of each channel and can be programmed up to a current of 31.5mA in steps of 500µA. Uniform display brightness is ensured through a better than 3% channel-to-channel current matching. Five internal registers are provided to set operational configuration and individual channel current programmation. A specific shutdown mode allows the device to retain the previously loaded configuration – operational and current programming – in order to be reused upon the next enabling.
The XRP7620 is designed to operate from a single cell lithium-ion battery or fixed 3.3V or 5.0V power rails and is available in a RoHS compliant, “green”/halogen free space saving 8-pin 2mm x 3mm DFN package
