SLA7082MS

Overview

The SLA7082MS is a unipolar stepper motor driver manufactured by Sanken Electric USA Inc. It integrates control and power stages using power MOSFET technology in a 23-ZIP(SLA)LF package. The device supports a logic supply voltage (VDD) of 3V to 5.5V and operates with a main power supply (VBB) ranging from 10V to 44V, with a maximum rating of 46V. It provides an output current capability of 2A per phase. The component features low-side output configuration for four channels and accepts parallel interfaces.

Feature Summary

• Integrates full drive circuitry including control logic and power MOSFET output stages for unipolar stepper motors.
• Includes built-in protection mechanisms against abnormal conditions such as motor coil open circuits or short circuits.
• Features thermal shutdown protection to ensure operational safety during overheating events.

Applications

• Driving inductive loads such as stepper motor windings
• General purpose motor driver applications requiring integrated control and power

Procurement Notes

Verify the specific suffix LF2151 if present, as it denotes the lead-free variant. Confirm the package type matches the required 23-ZIP(SLA)LF form factor. Ensure the design accommodates the specified voltage ranges and current limits. Check for RoHS compliance status if environmental regulations apply. Validate that the unipolar configuration aligns with the target motor wiring scheme.

Selection Notes

Select this component for applications requiring a single-chip solution for unipolar stepper motors. It is suitable where space constraints favor the ZIP package over discrete solutions. Consider the 2A output limit when sizing for load requirements. The integrated protection features reduce external component count compared to discrete driver designs.

Part Context

The SLA7082MS belongs to the SLA70xxMS series of motor drivers from Sanken Electric. These components are designed to simplify the interface between microcontrollers and stepper motors by combining logic and power electronics. The series typically targets cost-sensitive and compact motor control systems.

Replacement Considerations

SLA7081MPR is listed as a parametric equivalent substitute. Verify pin compatibility and electrical specifications before substitution.
