- General purpose motor drivers
Procurement Notes
Verify the specific suffix 'SLPTR-T' against official Allegro MicroSystems documentation to confirm tape-and-reel packaging and lead-free status. Ensure compatibility with standard SMD reflow profiles. Confirm that the 24-TSSOP-EP footprint matches your PCB layout requirements before finalizing procurement orders.
Selection Notes
Select this component when driving bipolar stepper motors requiring up to 2 A per phase. It is suitable for applications needing integrated control and power in a compact TSSOP form factor. Consider thermal management due to the exposed pad design. Verify input voltage ranges align with system power supplies between 8 V and 35 V.
Part Context
This part belongs to the A498x family of stepper motor driver ICs from Allegro MicroSystems. These devices are engineered to provide quiet, efficient, and smooth motion control. The A4986 specifically targets applications requiring robust DMOS technology for reliable operation in industrial and consumer electronics environments.
Replacement Considerations
Consult official datasheets for direct pin-to-pin substitutes within the A498x series. Verify electrical parameters such as current rating and voltage limits before substituting.
