The internal D/A converter proceeds by one bit at the rising edge of the input STEP pulse.
In addition, CW and CCW mode are switched by setting the FR pin.
In CW mode, the channel 2 current phase is delayed by 90° relative to the channel 1 current.
In CCW mode, the channel 2 current phase is advanced by 90° relative to the channel 1 current.
(9) Chopping frequency setting
For constant-current control, this IC performs chopping operations at the frequency determined by the capacitor
(Cchop) connected between the CHOP pin and GND.
The chopping frequency is set as shown below by the capacitor (Cchop) connected between the CHOP pin and GND.
Fchop = Ichop/ (Cchop × Vtchop × 2) (Hz)
Ichop : Capacitor charge/discharge current, typ 10
μA
Vtchop : Charge/discharge hysteresis voltage (Vtup-Vtdown), typ 0.5V
For instance, when Cchop is 200pF, the chopping frequency will be as follows :
Fchop = 10
μA/ (200pF × 0.5V × 2) = 50kHz
No.A1483-13/26
