Procurement Notes
Verify the specific suffix 'B' against official onsemi documentation to confirm pinout and electrical characteristics, as variations exist within the STK672 series. Ensure compatibility with existing PCB footprints and thermal management requirements before integration. Cross-reference datasheets for exact operating voltage and current limits to prevent design mismatches.
Selection Notes
Select this component for applications requiring a fully integrated solution for two-phase unipolar stepper motors. Consider its PWM control capabilities and built-in protection features when designing systems that demand robust motor driving without external complex circuitry. Verify package type and thermal dissipation needs against the specific application environment.
Part Context
This part belongs to the STK672 series of hybrid ICs from onsemi, specialized for stepping motor drivers. The series offers various configurations for different phase and polarity requirements. The STK672-622B-E specifically addresses two-phase unipolar applications, providing a compact alternative to discrete driver solutions.
Replacement Considerations
Check for direct substitutes within the STK672 family or other onsemi stepper driver lines. Verify pin-to-pin compatibility and electrical parameter equivalence before substituting.
