DESCRIPTIONThis Combo Motor Driver uses large scale inte-
gration to incorporate several functions into the
same chip.
1) Two unipolar stepper motor driver
2) A full bridge DC motor driver
3) Serial microprocesor interface
The power output stages are DMOS and the input
can be interfaced to a CMOS Microprocessor
logic.
The phase current in the unipolar stepper motor
windings is controlled by two external sensing re-
sistors in fixed frequency chopping mode. The os-
cillator block provides clocks each other 180° out
of phase to the two stepper motor driver in order
to avoid symultaneous current peaks.
For the DC motor driver is used a bridge; the
RMS voltage to supply this motor is fixed by a
BLOCK DIAGRAM
simple PWM open loop. The 3 motors are control-
led by the micro through 4 latches of 4 bit each.
The loading of these registers is in serial mode.
The I.C. operates at 5V supply for the logic and at
24V supply for the power stages. The packages
are SDIP42 and PLCC44 with 6 pins devoted to
ground and to sink out the heat produced by
power dissipation.
