STK6712BMK4
Unipolar Fixed-Current Chopper-Type
4-Phase Stepping Motor Driver
Overview
The STK6712BMK4 is a unipolar fixed-current chopper-
type 4-phase stepping motor driver hybrid IC (HIC) which
uses a MOSFET power device. The excitation sequence
signal is active low.
Applications
• Serial printer, line printer, and laser beam printer (LBP)
paper feed and carriage motor drivers
• PPC scanner and LBP paper feed drivers
• XY plotter pen drivers
• Industrial robot applications, etc.
Features
• This IC has the features of the STK6712BMK3, plus a
simultaneous input prevention circuit that protects the
IC from any malfunction of the excitation signal.
• Self-excitation design means chopping frequency is
determined by motor L and R. Supports chopping at
20 kHz or higher.
• Very low number of external components required.
• Wide operating supply voltage range (V_CC1 = 18 to
42V)
• Excitation sequence signal is active low, and is TTL
level for direct interfacing to the microcomputer and
gate array.
• The unipolar design enables use as a driver for hybrid,
PW, or VR type stepping motors.
• Supports W1-2 phase operation, with a dual Vref pin.
