Procurement Notes
Verify RoHS compliance status carefully, as datasheet records indicate conflicting information regarding RoHS3 certification for this specific part number. Confirm the active lifecycle status, as sources list the component as discontinued or obsolete. Ensure the 44-PLCC package variant matches the required PCB footprint and that the parallel interface logic aligns with the system design constraints before procurement.
Selection Notes
Select this component when a fully integrated solution for three-phase BLDC motors is required with a 3A current rating. The wide load voltage range up to 50V allows flexibility in power supply design. Consider the 44-pin PLCC package size and thermal characteristics for high junction temperature operation up to 150°C. Verify compatibility with parallel control interfaces and ensure the manufacturing lifecycle status meets long-term production requirements.
Part Context
The A3936 series represents Allegro MicroSystems' family of controllers for three-phase brushless DC motors. This specific variant integrates the necessary logic and power stages into a single DMOS chip. It simplifies motor drive designs by combining control algorithms with high-current output drivers, reducing the component count typically required for such applications.
Replacement Considerations
