STK672-400B-E

Overview

The STK672-400B-E is a thick-film hybrid IC designed as a unipolar, 2-phase stepping motor driver with PWM current control. It features an output current capacity of 2.4 A and operates within a supply voltage range of 5 V to 24 V. The device integrates power MOSFETs in the output stage alongside a built-in phase signal distribution IC. This integration allows for speed control based on external clock frequency and supports both 2-phase and 1-2 phase excitation modes. The package type is SIP22.

Feature Summary

Integrates power MOSFETs and a phase distribution IC for simplified control circuitry
Supports selectable 2-phase and 1-2 phase excitation modes
Includes internal noise filtering and Schmitt trigger circuits on the CLK input pin

Applications

Two-phase stepping motor drive in send/receive facsimile units
Office photocopiers
Printers

Procurement Notes

Verify the manufacturer designation carefully, as the part number originates from Sanyo Semicon Device. Confirm that the specific suffix matches the required electrical characteristics and package configuration. Ensure compatibility with existing thermal management solutions due to the hybrid IC construction. Cross-reference official datasheets to validate pinout assignments before implementation.

Selection Notes

Select this component when a compact solution for 2-phase stepper motors is required. It is suitable for applications needing microstep sinusoidal driving capabilities via external clock inputs. Consider the 2.4 A output rating against motor requirements. Evaluate the need for built-in protection functions if operating in high-noise environments.

Part Context

This component belongs to the STK672 series of thick-film hybrid integrated circuits. These devices are engineered specifically for stepping motor applications, combining power switching elements with logic control. The series offers various current ratings and phase configurations to accommodate different motor sizes and performance requirements in office automation equipment.
