STK672-410

Overview

The STK672-410 is a two-phase stepping motor driver manufactured by onsemi, designed for unipolar output configurations. It operates with a maximum collector-emitter voltage of 45 V and supports a minimum operating supply voltage of 4.75 V. The device utilizes a 19-pin SIP package with through-hole mounting. Typical switching frequency is specified at 47 kHz, and the component is rated for a maximum operating temperature of +150 °C.

Feature Summary

• Integrated driver for two-phase stepping motors
• Unipolar output configuration
• Through-hole SIP packaging

Applications

• Stepping motor control systems
• Industrial automation equipment
• Precision positioning devices

Procurement Notes

Verify the specific suffix and revision level against the official onsemi datasheet to ensure compatibility with your design requirements. Confirm that the 19-pin SIP form factor matches your PCB layout constraints. Check for RoHS compliance status if required by your manufacturing standards. Ensure thermal management solutions account for the specified maximum operating temperature limits during operation.

Selection Notes

Select this component when a dedicated two-phase unipolar stepper motor driver is required in a through-hole SIP package. Consider the 45 V maximum voltage rating and 4.75 V minimum supply voltage for power rail compatibility. Evaluate the 47 kHz typical switching frequency against system timing requirements. Verify that the physical dimensions of the 19-pin SIP package fit within the designated area on the circuit board.

Part Context

This part belongs to the STK672 series of stepping motor drivers from onsemi. The series includes various models such as the STK672-070-E and STK672-630AN-E, which share similar unipolar output characteristics but differ in pin counts and current ratings. The STK672-410 specifically addresses applications requiring a 19-pin interface for two-phase motor control.

Replacement Considerations

The STK672-080-E is identified as an industry-standard alternative within the same product family. Both components are designed for stepping motor driver applications. Verify pinout compatibility and electrical specifications before substitution.
