Figure 21. Low Voltage current Reduction Waveform with diagnostic-Flash and Main-Flash Phase

If the diagnostic flash should be short (e.g. 10ms) it is recommended to operate this diagnostic flash at slightly higher

vin_low_v_run setting compared to the main flash as shown in Figure 22:

Figure 22. Low Voltage current Reduction Waveform with short diagnostic-Flash and Main-Flash Phase

The different settings for vin_low_v_run allow a constant main flash current without dropping VIN below vin_low_v_run.
