Hello

I Request the Design Review.

Can you Review the Circuit?

    It had been forwarded to related engineers, but would have some delay because of holidays.

    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
