SLA7032M

Overview

The SLA7032M is a fully integrated unipolar stepper motor driver IC manufactured by Sanken Electric. It is housed in an 18-pin SSIP (Single In-line Package) with formed leads for through-hole mounting. The device combines control logic and power stages to drive two-phase stepper motors. Key electrical specifications include a minimum supply voltage of 10V and a load voltage range of 10V to 44V. It features two half-bridge output configurations designed for reliable motor control applications.

Feature Summary

• Fully integrated design combining control and power stages
• Supports two-phase unipolar stepper motor operation
• Half-bridge output configuration for dual coil driving

Applications

• Two-phase stepper motor control systems
• Unipolar stepper motor drivers
• Industrial automation equipment requiring precise motion control

Procurement Notes

Verify the specific package variant, as the SLA7032M may appear under different suffixes or revisions. Confirm that the 18-SSIP form leads match your PCB footprint requirements. Check current availability status, as this component may be classified as obsolete or discontinued by the manufacturer. Ensure compatibility with your system's voltage range of 10V to 44V before procurement.

Selection Notes

Select this component when a monolithic solution for unipolar stepper motors is required. It eliminates the need for external driver transistors due to its integrated power stage. Consider the 18-pin SSIP package constraints for board layout. Verify that the 44V maximum load voltage meets your motor's operational requirements. This IC is suitable for applications where space savings from integration outweigh the limitations of unipolar drive topology.
