Sanyo STK6711AMK4 Specifications
Any and all SANYO products described or contained herein do not have specifications that can handle
applications that require extremely high levels of reliability, such as life-support systems, aircraft’s
control systems, or other applications whose failure can be reasonably expected to result in serious
physical and/or material damage. Consult with your SANYO representative nearest you before using
any SANYO products described or contained herein in such applications.
SANYO assumes no responsibility for equipment failures that result from using products at values that
exceed, even momentarily, rated values (such as maximum ratings, operating condition ranges,or other
parameters) listed in products specifications of any and all SANYO products described or contained
herein.

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.
