CURRENT CONTROLLER FOR STEPPING MOTORS
DESCRIPTION
The L6506/D is a linear integrated circuit designed
to sense and control the current in stepping motors
and similar devices. When used in conjunction with
the L293, L298, L7150, L6114/L6115, the chip set
forms a constant current drive for an inductive load
and performs all the interface function from the con-
trol logic thru the power stage.
Two or more devices may be synchronized using
the sync pin. In this mode of operation the oscillator
in the master chip sets the operating frequency in all
chips.
