STK6712AMK4-C-E

Overview

The STK6712AMK4-C-E is a unipolar fixed-current chopper-type 4-phase stepping motor driver hybrid IC manufactured by Sanyo Denki. It integrates control and power stages for driving unipolar stepper motors. The device operates with a supply voltage range of 4.75V to 5.25V and supports an output current of 1.7A. It utilizes a SIP-16 package configuration and complies with RoHS standards, designed for applications requiring precise motor control in compact form factors.

Feature Summary

• Integrates fully integrated control and power stage functions for unipolar stepper motors
• Employs fixed-current chopper technology for stable motor operation
• Supports self-excitation type excitation sequences

Applications

• Serial printer paper feed and carriage motor drivers
• Laser beam printer (LBP) paper feed drivers
• PPC scanner paper feed mechanisms
• XY plotter pen drivers
• Industrial robot motion control systems

Procurement Notes

Verify the specific suffix C-E against official Sanyo Denki documentation to confirm environmental compliance status and pinout compatibility. Ensure that the SIP-16 package dimensions match the target PCB footprint requirements. Cross-reference the active product status with authorized distributors to confirm availability of genuine components. Validate that the operating temperature range aligns with the intended application environment specifications.

Selection Notes

Select this component for applications requiring a dedicated unipolar stepper motor driver with integrated power MOSFETs. Consider the 1.7A output capability when sizing thermal management solutions. Evaluate the 4.75V to 5.25V supply requirement against available system power rails. Compare the SIP-16 package constraints with board space limitations relative to alternative HIC packages.

Part Context

This part belongs to the STK6712 series of 4-phase stepping motor drivers from Sanyo Semicon Device. It shares functional similarities with variants like the STK6712BMK4 and STK6712AMK3, differing primarily in package type and specific electrical characteristics. The series is designed for office automation equipment and industrial control applications requiring reliable unipolar motor drive solutions.

Replacement Considerations

The STK6712BMK4 serves as a comparable unipolar fixed-current chopper-type driver within the same family. Verify pin-to-pin compatibility and electrical parameter alignment before substitution. Consult official Sanyo Denki cross-reference guides for confirmed equivalent parts.
