ELECTRICAL CHARACTERISTICS (continued)

(VIN = 3.6V, VGND = VPGND = 0V, VDD = 3.0V, TA = -40°C to +85°C, unless otherwise noted. Typical values are at TA = +25°C.) (Note 1)

Note 1: All devices are 100% production tested at TA = +25°C. Limits over the operating temperature range are guaranteed by design.

Note 2: LED current sink dropout voltage is defined as the voltage at which current drops 10% from the current level measured at 0.6V.

Note 3: Flash duration is from rising edge of FLEN until IFLED turns off (or returns to the movie current setting if MVON is high).
