(Rev.:2015)

Low voltage 16-bit constant current LED sink driver with output error detection and auto power-saving for automotive applications

STMicroelectronics 

Error detection mode functionality

STAP16DPPS05

Figure 24. Auto power-saving feature: first output TON

Note:

AM13672v1

Conditions:

– Temp. = 25 °C, VDD = 3.3 V, Vin = VDD, 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 TON condition as seen in the plot above.
