Figure 19: First output ON after switching from auto power saving to normal operating

condition

Electrical conditions:

temp. = 25 °C, Vdd = 3.3 V, Vin = Vdd, Vled = 3.0 V, Iset = 20 mA

Ch1 (Yellow) = SDI, Ch2 (Blue) = CLK, Ch3 (Purple) = LE, Ch4 (Green) = first output ON

When the device goes from AUTO power saving to normal operative condition,

the first output that switch ON shows TON condition as seen in the plot above.
