Hi,

When Auto-Retry mode used, delay pin should be pull-up.

How ohm should customer select if pull-up to 24V?

Suzuki-san,

In the datasheet for this part we recommend that the pull-up resistor between DELAY and IN be 100kΩ for the device's operating voltage range:

Hello Tim,

thank you for your response.

It looks abs max for delay pin is 7V. is it really okay to pull-up to 24V with 100kohm?

best regards,

Yes this is OK. The DELAY pin in auto-retry mode is essentially a high impedance input to a comparator so there is not going to be enough current to hit the 7V absolute max here.
