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