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.
