Power Management - Specialized Procurement Notes

Verify the obsolete status of this component before integration. Confirm that the specific suffix ZQFP matches the required pinout and thermal pad configuration for your design. Ensure compatibility with existing firmware or control logic if the PMU includes programmable features. Check for available lifecycle notifications from the manufacturer regarding final purchase dates.

Power Management - Specialized Selection Notes

Select this component when a consolidated power management solution is required for mobile platforms. The 48-QFN form factor suits designs needing multiple regulated outputs in a small footprint. Verify that the 195mA supply current fits within the system's total power budget. Ensure the 3V to 5.5V input range aligns with the primary battery or charging source voltage levels.

Power Management - Specialized Part Context

This part belongs to the AS3604 series of power management units from ams-OSRAM. These components are engineered to reduce bill-of-materials complexity in portable electronics by combining various power rails into one IC. The ZQFP designation indicates the specific lead-free, halogen-free tape-and-reel packaging variant suitable for automated surface-mount assembly processes.

Power Management - Specialized Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. As the component status is listed as obsolete, engineers must identify alternative PMUs with compatible pinouts and electrical specifications through independent cross-reference tools.
