توضیحات
Overview
The STK6712BMK4 is a unipolar fixed-current chopper type
4phase 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 (VCC1 = 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
