The SP7682 or SP7682A provides a complete LED backlight and flash solution that is designed to drive 4 low current LEDs for backlighting and a single channel high current output for a LED flash. The SP7682 and SP7682A have serial interfaces that can program the backlight LED current in steps of 0.5mA up to 31.5mA and flash LED current in steps of 10mA up to 500mA. The SP7682A uses two single line serial interfaces for programming the backlight current and flash current. The SP7682 uses an I2C serial interface which also allows programming active, standby and shutdown states, selecting flash timeout periods and switching individual LEDs for the backlight. The data is loaded into internal registers upon power up and stored while in shutdown. When the chip is enabled, the stored values set the LED currents. The SP7682/SP7682A automatically detects 1x, 1.5x or 2x operation for optimal efficiency.
