STK672-110-SL-E

Overview

The STK672-110-SL-E is a hybrid integrated circuit designed as a unipolar, fixed-current chopper driver for two-phase stepping motors. It incorporates power MOSFETs in the output stage and utilizes PWM current control to regulate motor speed. The device operates with a supply voltage range of 4.75V to 5.25V and supports load voltages between 10V and 42V. It delivers an output current of 2.1A and maintains an operating temperature capability up to 150°C.

Feature Summary

• Unipolar fixed-current chopper architecture for two-phase stepping motors
• Integrated power MOSFETs in the output stage
• Built-in PWM current control mechanism

Applications

• General purpose stepping motor control
• Industrial automation systems
• Precision positioning equipment

Procurement Notes

Verify the manufacturer origin, as Sanyo Semiconductor assets were acquired by ON Semiconductor. Confirm the specific suffix -SL-E matches the required packaging or tape-and-reel configuration. Ensure the component is sourced from authorized distributors to guarantee authenticity and traceability. Check for any updated datasheets reflecting the transition from Sanyo branding to ON Semiconductor specifications.

Selection Notes

Select this component when driving unipolar two-phase stepping motors requiring fixed-current chopper regulation. It is suitable for applications needing a supply voltage near 5V and load voltages up to 42V. Consider the 2.1A output current capacity and high thermal tolerance of 150°C for robust operation in demanding environments.

Part Context

This part belongs to the STK672 series of stepping motor drivers originally developed by Sanyo Semiconductor. The series includes variants like the STK672-040 and STK672-340-E, which share similar unipolar chopper technologies but may differ in phase configurations or current ratings. The STK672-110-SL-E specifically targets two-phase motor applications.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Users should consult official cross-reference guides from ON Semiconductor or verify compatibility with equivalent unipolar chopper drivers from other manufacturers based on electrical specifications.
