Procurement Notes
Verify the specific suffix ECGTR against the official datasheet to confirm the WLCSP package variant. Confirm RoHS compliance status through the manufacturer's documentation. Check for any Product Change Notices regarding packaging updates. Ensure the source document explicitly identifies this part as active or obsolete before procurement planning.
Selection Notes
Select this component when space constraints require a minimal footprint such as a 6-pin WLCSP. It is appropriate for applications requiring moderate current drive around 100mA. Verify that the 2.3V minimum supply voltage aligns with the system power rails. Consider thermal performance in the small package for continuous operation requirements.
Part Context
This part belongs to the A3907 series of motor drivers from Allegro MicroSystems. The series focuses on integrated solutions for small motors. The ECGTR designation indicates a specific tape-and-reel packaging format for the WLCSP version. It differs from other variants in package type and pin configuration.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Consult the manufacturer's cross-reference tools for equivalent components.
