The L6506 is a linear integrated circuit designed by STMicroelectronics to sense and control the current in stepping motors and similar devices. The chip set forms a constant current drive for an inductive load when used in conjunction with L293, L298, L7150, L6114/L6115, and performs all the interface function from the control 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.
The L6506 and L6506D are linear integrated circuits designed to sense and control current in stepping motors and similar devices. When used with drivers such as the L298, L298, L7150, or L6114/L6115, the chip set forms a constant current drive for an inductive load and performs all interface functions from control logic through the power stage. Two or more devices may be synchronized using the sync pin, allowing a master chip to set the operating frequency for all chips in the system.
The device features a common on-chip oscillator that drives a dual chopper to set the operating frequency for a pulse width modulated drive. It includes a comparator section for sensing input voltage and a logic section with TTL compatible inputs and outputs. The oscillator frequency is set by an external RC network on pin 1, and the peak current in each winding is programmed by selecting the value of the sense resistor and the reference voltage.
