STEPPER MOTER DRIVE NSKNSK
Introduction:
The A/D Stepper Moter Controller IC1 generates four phase drive
signals
for two phase bipolar and four phase unipolar step motors in
microcontroller
controlled applications. The motor can be driven in half step,
normal andwawe drive modes and on-chip PWM chopper circuits permit
switchmode
control of the current in the windings. A feature of this device
is that it
requires only clock,direction and mode input signals. Since the
phase are
generated internally the burden on the microcontroler and the
programmer
is greatly reduced. IC2 is a monolithic bridge high current
driver
