... CURRENT CONTROLLER FOR STEPPING MOTORS DESCRIPTION The L6506 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 ...

... R Internal Discharge Resistor i CIRCUIT OPERATION The L6506 is intended for use with dual bridge driv- ers, such as the L298, quad darlington arrays, such as the L7150, quad DMOS array such as L6114- L6115, or discrete power transistors to drive stepper motors and other similar loads. The main function of the device is to sense and control the current in each of the load windings ...
