The L6506/D is a linear integrated circuit designed to sense and control the current in steppingmotors and similar devices. When used in conjunctionwith the L293, L298, L7150, L6114/L6115,the chip set forms a constant current drive for an inductiveload and performs all the interfacefunctionfrom the con trol logic thru the power stage. Two or more devices may be synchronized using thesync pin. In this modeof operationthe oscillator in themasterchip sets theoperatingfrequencyin all chips.
