14 / 19 page  Auto power-saving feature AN3090 14/19 Doc ID16496 Rev 1 5 Auto power-saving feature This section explains the benefits of the auto power-saving feature of the STP16DPPS05 device. The plot in Figure 9 shows the IDD supply voltage consumption during normal mode and in the auto power-saving condition. Figure 9. IDD consumption in normal mode and auto power-saving condition In the plot above, IDD consumption (Ch4 green) falls after 16 CLK pulses (Ch2 blue) if no SDI data (Ch1 yellow) were latched by the LE/DM1 signal (Ch3 purple). When the first active data is available on the SDI pin (Ch1) and is latched by the LE/DM1 signal (Ch3), the device switches from auto power-saving mode to normal mode and IDD consumption rises to typical values. |
