Description

This Combo Motor Driver uses large scale integration 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 resistors in fixed frequency chopping mode. The L6285 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 asimple PWMopen loop. The 3 motors are controlled by the micro through 4 latches of 4 bit each.

The loading of these registers is in serial mode. The L6285 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.
