Overview
The SLA7071MPR is a two-phase unipolar stepper motor driver from the Sanken SLA707xM series, integrating low-power CMOS logic with high-current power FET outputs. It provides complete control and drive for two-phase unipolar stepper motors within a Power Multi-Chip Module (PMCM). The device supports full- and half-step operation externally selectable, featuring internal fixed off-time and pulse-width modulation (PWM) current control. It operates with a motor supply voltage up to 44V, load supply voltage between 10V and 44V, and logic supply voltage from 3V to 5.5V.
Feature Summary
- Integrates CMOS sequencing logic with high-voltage power FET outputs for complete motor control
- Features internal fixed off-time and PWM control for precise output current regulation
- Supports external selection of full-step and half-step excitation modes
- Includes clamp diodes for protection against inductive transients
Applications
- Personal Printer Computers (PPC)
- Printers
- Office Automation Equipment
Procurement Notes
Verify the specific suffix 'MPR' against the manufacturer's official datasheet to confirm package type and tape-and-reel specifications. Ensure input logic levels are compatible with the 3V to 5.5V range, as TTL or LSTTL inputs may require pull-up resistors for proper high-state definition. Confirm thermal requirements for the PMCM package under maximum load conditions.
Selection Notes
Select this component when a fully integrated solution for two-phase unipolar stepper motors is required without complex microprocessor programming. It is suitable for applications where high-frequency control lines are unavailable or when minimizing interface complexity is a priority. Consider the 2A sink capability and 46V withstand voltage for appropriate load matching.
Part Context
The SLA7071MPR belongs to the SLA707xM series of unipolar stepper motor drivers manufactured by Sanken Electric USA Inc. This series combines CMOS logic with power MOSFET technology to offer robust motor driving capabilities in a compact multi-chip module format. The family includes variants supporting different step resolutions and current ratings.
Replacement Considerations
The STA7131MPR is listed as a parameter-equivalent substitute by distributors. Verify functional compatibility and pinout alignment before substitution.
