Hello
I Request the Design Review.
Can you Review the Circuit?

Hello,
Your schematic indicates that you wish to set your timer for a 60min interval using a network of two parallel 137k resistors, equivalent resistance of 68.5k.
If we refer to Table 3 in the datasheet, we can see that this resistance value puts the time interval to between 10 and 20 minutes.
For your desired 60min interval, we recommend a resistance of 124.91k to ground from the DELAY/M_DRV pin, or a 221k and 287k parallel resistor network.
Can you confirm that you intend for a 60min interval? And can you also confirm that you intend to operate the part in One-Shot mode rather than Timer mode?
Regards,
Adam
