Ordering number:ENN5165

Thick Film Hybrid IC

STK6711AMK4

4-Phase Stepping Motor Driver

Unipolar Self-Excitation Type (IO=1.5A)

Overview

The STK6711AMK4 is a unipolar fixed-current choppertype self-excitation 4-phase stepping motor driver hybrid IC which uses MOSFET power devices. The exci-

tation sequence signal is active-high.

Applications

•Serial printer, line printer, and laser beam printer (LBP) paper feed and carriage motor drivers.

•PPC scanner and LBP feed drivers.

Features

•Simultaneous ON prevention circuit built-in to prevent driver breakdown due to simultaneous ON control signals from the control system’s microcontroller, etc.

•Self-excitation design means chopping frequency is determined by motor L and R. Supports chopping at 20kHz or higher.

•Two 0.33Ω current detection resistors built-in for fixedcurrent chopping operation.

•Wide operating supply voltage range (18 to 42V for motor drive).

•Unipolar design enables use as a driver for hybrid, PM, or VR-type stepping motors

•Supports W1-2 phase operation, with dual Vref pins.
