Procurement Notes
Verify the exact suffix and revision level when sourcing, as manufacturing status may vary. Confirm RoHS compliance and environmental declarations against current datasheets. Check for end-of-life notifications or product change notices from onsemi. Ensure the 14-MFPS package footprint matches your PCB design requirements before procurement.
Selection Notes
Select this component for applications requiring integrated control and power stages for two-phase unipolar motors. Verify that the 6.4V to 7V logic supply and 12V/24V load voltage ranges align with system power rails. Consider the 14-MFPS package size for space-constrained designs. Evaluate thermal performance based on the specific mounting conditions and ambient temperature limits.
