Overview
The SLA7072MRF is a monolithic integrated circuit designed as a driver for two-phase unipolar stepper motors, manufactured by Sanken Electric. It integrates power output stages with control logic to manage motor phases directly from microprocessor signals. The device supports full-step and half-step driving modes, providing efficient commutation for stepper motor applications. It features built-in protection mechanisms to ensure reliable operation under varying load conditions.
Feature Summary
- Integrates dual H-bridge output stages for direct drive of two-phase unipolar stepper motors
- Supports selectable full-step and half-step operating modes for smooth motion control
- Includes internal protection circuits against overcurrent and thermal overload
Applications
- Two-phase unipolar stepper motor control systems
- Industrial automation equipment requiring precise positioning
- Office automation devices such as printers and scanners
Procurement Notes
Verify the specific suffix 'R' indicates tape and reel packaging configuration when sourcing components. Confirm that the part number matches the exact voltage and current ratings required for the target application. Ensure compatibility with the system's logic voltage levels before integration into the design.
Selection Notes
Select this component for applications requiring integrated control and power stages for unipolar stepper motors. Evaluate the thermal performance requirements based on the expected duty cycle and ambient temperature. Compare the package type and pinout against the existing PCB layout constraints to ensure mechanical fit.
Part Context
This part belongs to the SLA7070M(P)R through SLA7078M(P)R series of two-phase unipolar stepper motor drivers released by Sanken Electric in February 2006. The series provides various configurations for different motor current and voltage requirements within the same functional family.
Replacement Considerations
Check for other members of the SLA7070M series with compatible electrical specifications. Verify pin-to-pin compatibility if substituting with similar stepper driver ICs from other manufacturers.
