Power Management - Specialized Procurement Notes

Verify the specific suffix (e.g., DDD vs. DDD-T) against official documentation, as it indicates tape-and-reel packaging rather than functional differences. Confirm RoHS3 compliance status. Note that this part number is obsolete; check for valid alternative package types or newer revisions through Analog Devices channels before procurement planning.

Power Management - Specialized Selection Notes

Select this component for designs requiring a compact PMIC for single-cell Li-ion powered mobile devices. Ensure the PCB layout accommodates the 12-WQFN exposed pad for thermal management. Verify that the required input voltage range of 2.5V to 5.5V aligns with the system battery profile and that the 180µA supply current meets the standby power requirements.

Power Management - Specialized Part Context

The MAX8890 belongs to the Maxim Integrated portfolio, now part of Analog Devices. It is a specialized PMIC intended for cellular applications. The ETCDDD suffix denotes the specific 12-WQFN package variant. This series addresses the power efficiency needs of early-generation mobile phones using single-cell batteries.
