Notes:
(1) Stresses above those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings
only, and functional operation of the device at these or any other conditions outside of those listed in the operational sections of this
specification is not implied. Exposure to any absolute maximum rating for extended periods may affect device performance and reliability.
(2) The VBAT pin voltage should be at least 3V greater than the total sum of the LED forward voltages in order to operate at nominal LED
current.
(3) During power-up, the slew rate of the input supply should be greater than 1µs for every 5V increase of VBAT.
