TPL5111: Schematic Review for one shot feature

Part Number: TPL5111


I want to use tpl5111 as one-shot mode. 
I Want output power from DRVn to turn on mosfet(mosfet is basically running set of LEDs)Schematic.jpg when main power is applied to the IC. And after set time of 30 min it turns off until I apply power again.  

Above is the circuit for that. Kindly review it.
