TPS65988DJ: what is reasonable power consumption if sleep mode is entered?

user4760726

Part Number: TPS65988DJ

Hi team,

The power consumption for sleep mode in datasheet is 55uA (typecial). Is there a reasonable (maximum) value for sleep mode can be provided in worst case? Customer would like to know. please advised.

Best Regards,

Hi Leroy,

The worst-case power consumption in sleep mode is dependent on the GPIO usage and circuitry connected on LDO_3V3. Since there are many options for these items, the maximum power consumption in sleep mode is not specified.

Thank you,
Eric

Eric,

Thanks for your reply. Do you think we can add the maximum current that can be loaded for the LDO_3V3 and GPIO into account to have a data to share with customer? For example, the maximum ILDO_3V3_EX is 25mA, so it would be about 25.055mA (25mA +55uA) for the worst case? Any thought about it?

Best Regards,

Hi Leroy,

That would be a reasonable assumption for the max current during sleep mode. However, you also need to take into account the current consumed by GPIOs during run-time so this value may fluctuate.

Thank you,
Eric
