SLA7066M

Overview

The SLA7066M is a monolithic integrated circuit designed for driving two-phase unipolar stepper motors. It operates with a supply voltage range of 3V to 5.5V and supports load voltages from 10V to 44V. The device features an output current capacity of 3A per phase and utilizes NMOS technology. It is housed in a 21-SIP (Single In-line Package) format, suitable for through-hole mounting. The component integrates full control and power stages for efficient motor management.

Feature Summary

• Integrated driver for two-phase unipolar stepper motors
• Full integration of control logic and power output stages
• NMOS-based output configuration for high current drive
• Compatible with brushed DC motors and stepper applications

Applications

• Two-phase unipolar stepper motor control systems
• Brushed DC motor driving circuits
• General-purpose motor driver modules requiring integrated control

Procurement Notes

Verify the specific suffix variant required for your application, as Sanken uses suffixes like LF2102 to denote specific revisions or packaging types. Confirm that the 21-SIP package dimensions match your PCB layout constraints. Check current availability status as this component may be subject to obsolescence notices. Ensure supply chain sources provide original manufacturer documentation to guarantee authenticity and technical accuracy.

Selection Notes

Select the SLA7066M when a single-chip solution for two-phase unipolar stepping is required. It is appropriate for designs needing up to 3A output current with low-voltage logic control. Consider thermal management requirements due to the SIP package form factor. Verify compatibility with the intended motor's voltage and current specifications before implementation.

Part Context

This component belongs to Sanken's series of motor driver ICs, specifically targeting unipolar stepper applications. It consolidates gate drive, logic control, and power MOSFET outputs into a single package. The SLA7066M represents a compact solution for reducing board space compared to discrete driver implementations.
