L6506, Драйвер управления шаговыми электродвигателями
The L6506 is a linear integrated circuit Current Controller designed to sense and control the current in stepping motors and similar devices. When used in conjunction with the L293, L298, L7150 and L6114/L6115 the chip set forms a constant current drive for an inductive load and performs all the interface function from the control logic through the power stage. Two or more devices may be synchronized using the synchronized pin. In this mode of operation the oscillator in the master chip sets the operating frequency in all chips.
