STK672-610

Overview

The STK672-610 is a monolithic integrated circuit designed for driving two-phase stepping motors. It utilizes a unipolar output configuration and is housed in a 19-pin Single In-line Package (SIP). The device integrates control logic and power drivers to manage motor phases directly from standard logic inputs.

Feature Summary

• Integrates driver circuits for two-phase unipolar stepping motors
• Accepts standard logic level input signals for step and direction control
• Designed for robust operation within specified thermal limits

Applications

• Two-phase permanent magnet stepping motor control
• Hybrid electric stepping motor actuation
• Industrial automation positioning systems

Procurement Notes

Verify current manufacturing status as the component may be obsolete or subject to specific factory ordering requirements. Confirm package integrity and pinout compatibility with existing PCB layouts before procurement. Consult official onsemi documentation for final electrical specifications and handling precautions.

Selection Notes

Select this component for applications requiring direct drive of two-phase unipolar stepper motors without external power transistors. Ensure the load current remains within the device's rated capacity. Verify that the operating voltage range matches the system's logic and motor supply levels.

Part Context

This part belongs to the STK672 series of motor drivers manufactured by onsemi. These components are classified under Motor / Motion / Ignition Controllers & Drivers. The series provides integrated solutions for stepping motor applications, combining control and power stages in a single SIP package.

Replacement Considerations

The STK672-080-E is a comparable alternative within the same product family. Both devices serve as stepping motor drivers. Verify pin compatibility and electrical ratings when substituting.
