Figure 24. Auto power-saving feature: first output T_ON
Note:
AM13672v1
Conditions:
– Temp. = 25 °C, V_DD = 3.3 V, Vin = V_DD, VLed = 3.0 V, Iset = 20 mA
– Ch1 (yellow) = CLK, Ch2 (blue) = SDI, Ch3 (purple) = LE/DM1, Ch4 (green) = IDD
When the device goes from auto power-saving to normal operating condition, the first output
switching ON shows the T_ON condition as seen in the plot above.
