Backlight Driver With I/O Expander

The ADP5520 is a versatile single-chip, white LED backlight driver with a user configurable I/O expander. This device fits handset applications where the flip or slider section of the phone requires backlighting, I/O signaling and detecting, auxiliary LED lighting, and keypad functions. By incorporating an I 2 C- compatible serial Interface and a single line interrupt, the ADP5520 significantly reduces the total number of lines required to Interface with the baseband processor across the hinge flex.
