Procurement Notes

Verify the manufacturer source, as Fairchild Semiconductor assets are now part of ON Semiconductor. Confirm the specific suffix 'B' matches the required pinout and electrical characteristics from the official datasheet. Check for RoHS compliance status and ensure the component is available in the active lifecycle stage rather than discontinued or obsolete status.

Selection Notes

Select this IC for applications requiring a compact solution for driving multiple motors in portable media devices. The integration of the DC/DC controller and battery charger reduces external component count. Ensure the design accommodates the thermal requirements due to the integrated power stages and verify compatibility with the system's battery voltage range.

Part Context

The FAN8038B belongs to a family of multi-channel motor drive ICs produced by Fairchild Semiconductor. Related parts in the series include the FAN8038C and other variants like the FAN8033 and KA3030D, which offer different channel counts. These components are specifically engineered for portable audio and optical media players requiring efficient motor control and power management.

Replacement Considerations

Public confirmed substitute part numbers are not provided in the available documentation. Users should consult the manufacturer's cross-reference tool for parametrically similar parts if direct substitution is required.
