7.4.3 One-Shot Mode

During one-shot mode (EN/ONE_SHOT = LOW), the TPL5111 generates just one pulse at the DRVn pin which lasts according to the programmed time interval. In one-shot mode, other DRVn pulses can be triggered using the DELAY/M_DRV pin. If a valid manual power ON occurs when EN/ONE_SHOT is LOW, the TPL5111 generates just one pulse at the DRVn pin. The duration of the pulse is set by the programmed time interval. Also in this case, if a DONE signal is received within the programmed time interval (minus 50 ms), the DRVn output is asserted LOW. See Figure 9 and Figure 10.
