7.4.3 One-Shot Mode

During one-shot mode (EN/ONE_SHOT = LOW), the TPL5110-Q1 generates just one pulse at the DRV pin which lasts according to the programmed time interval. In one-shot mode, other DRV pulses can be triggered using the DELAY/M_DRV pin. If a valid manual power ON occurs when EN/ONE_SHOT is LOW, the TPL5110-Q1 generates just one pulse at the DRV 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 50ms), the MOSFET connected to the DRV pin is turned off. See Figure 7-2 and Figure 7-3.
