Overview
The SLA7029M is a two-phase stepper motor unipolar driver IC manufactured by Sanken Electric USA Inc. It employs a constant-current chopper control method with self-excitation PWM current control and fixed off time. The device integrates full drive, control, and power stages using Power MOSFET technology. It supports parallel interfaces and operates within a supply voltage range of 10V to 44V. The component is housed in an 18-ZIP (18-SSIP molded lead) package designed for through-hole mounting.
Feature Summary
- Integrates constant-current chopper control with self-excitation PWM current regulation
- Combines full drive, control logic, and power output stages in a single unit
- Utilizes Power MOSFET technology for efficient switching performance
Applications
- Two-phase unipolar stepper motor control systems
- Industrial automation equipment requiring precise step resolution
- General-purpose motor driver circuits
Procurement Notes
Verify the specific datasheet revision and ordering suffix when sourcing, as variations may exist between distributors. Confirm that the 18-ZIP package matches your PCB footprint requirements. Ensure compatibility with the target motor's current rating and supply voltage limits before integration. Check for RoHS compliance status if required by your manufacturing standards.
Selection Notes
Select this component for applications requiring integrated unipolar stepper motor control without external discrete drivers. The fixed off-time PWM control simplifies thermal management compared to linear regulators. Consider the 18-pin SIP package constraints for board layout. Verify that the 1.5A output capability meets the load requirements of the intended stepper motor coils.
Part Context
The SLA7029M belongs to Sanken's SLA70xx series of motor driver ICs. This family includes variants such as the SLA7024M and SLA7027MU, which share similar architectural features but differ in pin counts or current ratings. These components are designed to replace older discrete driver solutions, offering higher integration and reduced system complexity for two-phase stepping applications.
Replacement Considerations
The SMA7029M is listed as a similar part number within the same product line. Verify pinout compatibility and electrical specifications against the original design requirements before substitution.
