DP83867E: Power consumption in nReset

Bernhard Boehmer

Part Number: DP83867E

Hello TI,

What is the expected power consumption of the DP83867E in nReset, please? This was specified for some of the other TI Phys, eg DP83825. Is this a expected to be a low(er)-power mode for the DP83867?

Hi Bernhard,

Please see the following app note for power consumption numbers of the DP83867: SNLA241

Power consumption while in reset is not measured, but please see the numbers for other low power modes.

Thanks,

David

Hello David,

Thank you for the response. Is it safe to hold the part in Reset indefinitely? Is the power consumption expected to be lower than that of the normal operating modes?

Hi Bernhard,

Yes, it is safe to hold the part in reset indefinitely. As stated, we do not have the exact power consumption numbers while in reset, but yes, the power consumption is expected to be lower than that of normal operating mode. If the intention is to have a low power mode, though, you are likely better off using one of the modes described in SNLA241.

Thanks,

David
