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.
