STK6712BMK4-E

Overview

The STK6712BMK4-E is a hybrid thick film integrated circuit manufactured by onsemi, classified under Motor / Motion / Ignition Controllers & Drivers. It functions as a stepping motor driver designed for unipolar fixed-current chopper-type operation with four phases. The component utilizes a Single In-line Package (SIP) configuration featuring sixteen terminals with a pitch of 2.54 mm. Constructed from plastic/epoxy material, it operates within a power supply range of 5 to 36 volts. This device is part of the PMIC - Power Management ICs subcategory and is intended for industrial motion control applications requiring robust hybrid technology.

Feature Summary

• Unipolar fixed-current chopper-type architecture for precise stepping motor control
• Four-phase capability integrated into a single hybrid thick film package
• Wide operating voltage range supporting diverse power supply environments

Applications

• Stepping motor driver circuits in industrial automation systems
• Motion control modules requiring unipolar chopper drive topology
• Hybrid thick film integration for specialized ignition or motor controllers

Procurement Notes

Verify current manufacturing status and availability directly with onsemi or authorized distributors, as this component may be subject to special order requirements. Confirm RoHS compliance details and specific packaging configurations prior to procurement. Ensure that the SIP16 pinout and electrical specifications match the target design requirements. Request official documentation to validate the latest production revisions and any potential obsolescence notices associated with this part number.

Selection Notes

Select the STK6712BMK4-E when a dedicated hybrid solution for unipolar four-phase stepping motors is required. Its fixed-current chopper design simplifies driver circuitry compared to discrete implementations. Consider the 5V to 36V operating range for compatibility with existing power rails. The SIP16 package facilitates through-hole mounting, which may be preferred for high-reliability or high-power thermal management scenarios over surface-mount alternatives.

Part Context

This component belongs to onsemi's portfolio of hybrid thick film integrated circuits, specifically tailored for motor and motion control applications. It falls under the broader category of Power Management ICs but serves a distinct function as a dedicated stepper driver. The STK series typically offers robust performance in demanding environments, leveraging hybrid technology to combine thin-film precision with thick-film durability for reliable long-term operation in industrial settings.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source data. Verify if other models within the STK series share identical pinouts and electrical characteristics before considering cross-referencing. Consult manufacturer documentation for direct replacements or updated generations of this hybrid stepping motor driver.
