Overview
The SLA7060M is a unipolar stepper motor translator/driver manufactured by Sanken Electric. It integrates low-power CMOS logic with high-current, high-voltage power FET outputs to provide complete control and drive for two-phase unipolar stepper motors. The device features an internal sequencer for microstepping operation and pulse-width modulation (PWM) control of output current. It is housed in a Power Multi-Chip Module (PMCM) package, specifically the 21-ZIP configuration, designed for through-hole mounting.
Feature Summary
- Integrates internal sequencer for microstepping operation
- Provides PWM constant-current motor drive capability
- Features avalanche-rated NMOS outputs with advanced body diodes
- Compatible with 3.3 V or 5 V control signals
Applications
- Two-phase unipolar stepper motor control systems
- Industrial equipment requiring precise motor positioning
- Automotive auxiliary systems utilizing high-voltage drivers
- Home appliances with integrated motor drive requirements
Procurement Notes
Verify the specific suffix designation against the manufacturer's official datasheet to ensure correct pinout and electrical characteristics. Confirm that the 21-ZIP package variant matches the target PCB footprint. Ensure compatibility with the intended supply voltage range and thermal management requirements before finalizing procurement specifications.
Selection Notes
Select this component when a monolithic solution for two-phase unipolar stepper motors is required. It eliminates the need for external phase-sequence tables or complex interface programming. Consider its integration of PWM control and internal clamping diodes for simplified circuit design compared to discrete driver solutions.
Part Context
This part belongs to the SLA7060 series of unipolar stepper motor translator/drivers. It shares functional similarities with other members like the SLA7062M but may differ in specific packaging or minor electrical ratings. The series is characterized by combining CMOS logic with high-power FET outputs in a multi-chip module format.
Replacement Considerations
The SLA7062M is documented as a similar part number within the same product family. Verify pin-to-pin compatibility and specific electrical parameter alignment before substitution.
