1. Backlight and Flash Configuration within a part number is configured though the I2C serial interface. For example, clearing the MEQS flag (set to “0”) in the AAT2860-1’s REG2
register will configure BL1-BL4 LED outputs as MAIN and BL5-BL7 outputs as SUB.
2. Stresses above those listed in Absolute Maximum Ratings may cause permanent damage to the device. Functional operation at conditions other than the operating conditions
specified is not implied. Only one Absolute Maximum Rating should be applied at any one time.
3. Derate 20 mW/°C above 25°C ambient temperature.
4. Mounted on a FR4 circuit board.
