STA7130MPR

Overview

The STA7130MPR is a unipolar stepper motor driver IC manufactured by Sanken Electric USA Inc. It features an integrated sequencer supporting 1, 1/2, 1/4, and 1/8 step resolutions. The device utilizes power MOSFET technology with a parallel interface and half-bridge output configuration (2 channels). It operates within a supply voltage range of 10V to 44V and delivers an output current of 1A. Designed for through-hole mounting, it is housed in a 18-ZIP (18-SSIP molded lead) package. The component supports a junction temperature range from -20°C to 150°C.

Feature Summary

• Integrates full control logic and power stage for unipolar stepper motors
• Supports multiple excitation modes including full, half, quarter, and eighth steps
• Built-in sequencer simplifies drive circuit design

Applications

• General purpose stepper motor control systems
• Industrial automation equipment requiring precise positioning
• Office automation devices such as printers or scanners

Procurement Notes

Verify the specific suffix MPR against the manufacturer's official datasheet to confirm packaging and tape-and-reel specifications. Ensure the ordering part number matches the exact electrical characteristics required for the target application. Cross-reference the RoHS status and moisture sensitivity level (MSL 1) with project compliance requirements before finalizing procurement.

Selection Notes

Select this component when driving unipolar stepper motors with voltages up to 44V and currents up to 1A. The integrated sequencer reduces external component count compared to discrete solutions. Consider the 18-ZIP through-hole package for applications requiring robust mechanical mounting. Verify that the parallel interface compatibility aligns with the system controller.

Part Context

The STA7130MPR belongs to the STA7130 series of unipolar driver ICs from Sanken Electric. This series includes variants such as the STA7131MPR and STA7132MPR, which share similar functional architectures but may differ in specific pinouts or internal configurations. These drivers are designed to replace older discrete driver circuits in compact form factors.

Replacement Considerations

Consult the official Sanken Electric datasheet for the STA7130 series to identify direct cross-model equivalents like the STA7131MPR or STA7132MPR. Verify pin-to-pin compatibility and electrical parameter alignment before substitution.
