| Description | High-performance, high-current unipolar stepper motor driver IC integrating multi-chip power Darlington transistors, constant-current PWM chopping circuitry, and protection networks for precision positioning automation. |
| Stock Status | In Stock |
| Origin | Original Factory |
Product Overview
The SLA7026M is Sanken’s robust unipolar 2-phase stepper motor driver in ZIP-18 packaging, built for industrial high-precision positioning equipment. This monolithic IC integrates Darlington power arrays, pre-drivers and constant-current PWM chopping circuits to deliver stable winding current, strong low-speed torque and low micro-step jitter. Embedded blanking circuits filter switching noise to simplify PCB design, and its high-dissipation ZIP package serves as a reliable drive core for office automation, conveyor systems and heavy factory machinery.
Core Advantages
High-Current Power Stage Integration
Combines heavy-duty Darlington transistors directly on-chip, effortlessly delivering up to 3A of continuous peak current per phase without needing bulky external discrete MOSFET arrays.
Advanced Constant-Current PWM Chopping
Employs an intuitive internal PWM chopping mechanism that maintains high system power efficiency and consistent magnetic flux, preventing motor stalls even during abrupt load changes.
Simplified Logic Command Interface
Designed with standard logic-level control boundaries that integrate directly with entry-level microcontrollers, PLCs, or CNC interface modules without complex translation components.
Thermally Optimized ZIP Packaging
Housed in Sanken’s specialized high-power ZIP package format, enabling simple attachment to single or multi-stage aluminum heatsinks to safely handle continuous heavy torque operations.

Frequently Asked Questions
Q1: Is your current stock inventory of the SLA7026M motor driver completely authentic and original?
A: Yes, we guarantee that all SLA7026M component modules in our warehouse stock are 100% brand-new, factory-original parts from Sanken Electric. They are strictly handled, tracked, and dispatched under strict anti-static ESD-safe security boundaries.
Q2: Can the SLA7026M be deployed to drive standard bipolar stepper motor configurations?
A: No, the SLA7026M is explicitly designed and optimized internally for unipolar stepper motor architectures (which usually feature 5-wire, 6-wire, or 8-wire setups). For true bipolar motor projects, please consult our specialized bipolar bridge collection matrix.
Q3: Is it mandatory to install an external metal heatsink onto the ZIP-18 frame during everyday deployment?
A: For light workloads with output currents well under 1.0A per phase, the device can operate on air-cooled parameters. However, for applications pushing closer to its 3A peak capacity, installing a properly matched aluminum heatsink is highly recommended to prevent structural thermal overload.
Q4: How can our technical group request complete system application notes, terminal layout blueprints, or bulk quantity price tiers?
A: Please complete our Quick Inquiry web form on this page with details about your processing parameters. Our application support desk will process your inquiry and dispatch the available technical documentation package within 24 hours.
