How to Calculate Set Current
This IC drives the motor, controlling the PWM constant current in reference to the frequency of CR
oscillator.
At that time, the maximum current value (set current value) can be determined by setting the sensing
resistor (RRS) and reference voltage (Vref).

1/5.0 is Vref (gain): Vref attenuation ratio. (for the specifications, see the electrical characteristics.)
For example, when applying Vref = 3 V and torque = 100% to drive out IOUT of 0.8 A, RRS = 0.75 (0.5 W
or more) is required.
(for 1-2 phase excitation with 71% of torque, the peak current should be set to 100%).
How to Calculate the Chopping and OSC Frequencies
At constant current control, this IC chops frequency using the oscillation waveform (saw tooth waveform)
determined by external capacitor and resistor as a reference.
The TB62206F requires an oscillation frequency of eight times the chopping frequency.
The oscillation frequency is calculated as follows:

For example, when Cosc = 560 pF and Rosc = 3.6 k are connected, fCR = 813 kHz.
At this time, the chopping frequency fchop is calculated as follows:
fchop = fCR/8 = 101 kHz
