SLA7076MPR

Overview

The SLA7076MPR is a two-phase unipolar stepper motor driver from the SLA707xM series by Sanken Electric. It integrates low-power CMOS logic with high-current, high-voltage power FET outputs in a Power Multi-Chip Module (PMCM). The device provides complete control and drive for unipolar stepper motors, featuring internal fixed off-time and pulse-width modulation (PWM) current control. It supports full, half, quarter, eighth, and sixteenth-step operation. Key electrical specifications include a load supply voltage range of 10V to 44V, a logic supply voltage of 3V to 5.5V, and an output current capability of up to 1.5A per phase. The component operates within a junction temperature range of -20°C to 150°C.

Feature Summary

• Integrates sequencing logic, direction control, and synchronous/asynchronous PWM operation within a single module.
• Features NMOS outputs capable of sinking high currents while withstanding high off-state voltages.
• Includes internal clamp diodes for protection against inductive transients.
• Eliminates the need for complex microprocessor interfaces or phase-sequence tables.

Applications

• Personal Printer Copiers
• Office Automation Equipment

Procurement Notes

Verify the specific suffix 'MPR' against the manufacturer's datasheet to confirm pinout and packaging details, as variations exist within the SLA707xM family. Ensure compatibility with the target unipolar stepper motor voltage and current requirements before integration. Confirm RoHS compliance status if required for the final assembly process.

Selection Notes

Select this component for applications requiring integrated control and power stages without external sequencers. It is suitable where TTL or LSTTL logic inputs are available. Consider the 23-pin package size and thermal dissipation capabilities relative to the enclosure design. Verify that the required step resolution (up to 1/16) aligns with the application's precision needs.

Part Context

This part belongs to the SLA707xM series, which includes variants like SLA7075M, SLA7076M, SLA7077M, and SLA7078M. These devices share a common architecture but may differ in current ratings or specific feature sets. The SLA7076MPR specifically denotes the unipolar stepper motor driver variant within this family, designed for general-purpose motion control tasks.

Replacement Considerations

Parameter-equivalent substitutes include SLA7076MR and SLA7076MPRT from Sanken Electric USA Inc. Verify pin compatibility and thermal performance when substituting.
