DS250DF410: minimum EN_SMB=0 time to reset the device at SMBus Slave Mode

Kazuhiko Hirano

Part Number: DS250DF410

Hello,

When SMBus Slave Mode (EN_SMB=1), to reset to make the device to be held in reset, how much time does the READ_EN_N have to be LOW at the minimum?

Best regards,

Hi Hirano-san,

Unfortunately, this hasn't been characterized on this device, but typically the response for pin state changes on these devices is very quick, on the order of 1-10us. For example, see that response time for crosspoint control on a similar device is ~1us.

I think we can confidently recommend 1 ms to the customer. This will give a large margin.

Thanks,

Drew
