7.5.2 Manual MOSFET Power ON Applied to the DELAY/M_DRV Pin

If VDD is connected to the DELAY/M_DRV pin, the TPL5110-Q1 recognizes this as a manual MOSFET Power ON condition. In this case the time interval is not set. If the manual MOSFET Power ON is asserted during the POR or during the reading procedure, the reading procedure is aborted and is re-started as soon as the manual MOSFET Power ON switch is released. A pulse on the DELAY/M_DRV pin is recognized as a valid manual MOSFET Power ON only if it lasts at least 20ms (observation time is 30ms). The manual MOSFET Power ON may be implemented using a switch (momentary mechanical action).

If the DRV is already LOW (MOSFET ON) the manual MOSFET Power ON is ignored.
