ST L6506 L6506D handbook
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.

What is the minimum value for resistor R1 in the oscillator circuit?
The minimum value for R1 of 700Q (1 KQ —30 %) should be used to guarantee the required pulse width.
