Calculation of Set Current
To obtain the motor setting current value (peak current), values of RRS, Vref and Torque should be determined
according to the equation below.

1/Vref (gain): 1/Vref attenuation ratio is 1/4.0 (typ.).
For example,
to input Vref = 1 V and Torque = 100% and to output Iout = 0.25 A,
RRS = 1.0 (0.1 W or more) is required.
Formulas for Calculating Reference Oscillation Frequency (chopping reference
frequency)
The M_osc oscillation frequency (fosc_M) and, chopping frequency (fchop) can be calculated by the following

Example: When COSC = 560 pF is connected, M_osc = 813 kHz.
At this time, the chopping frequency fchop is: fchop = fosc/8 = 101 kHz.

DCDC Converter Oscillating Frequency
fDCDC (DCDC PWM frequency) = 50 ()/(0.8 × COSC_D) (Hz)
PWM frequency for DCDC block is about 100 kHz when COSC_D is 620 pF.
Example:
COSC_D = 680 pF: 91 kHz
= 620 pF: 100 kHz
= 560 pF: 111 kHz
= 510 pF: 122 kHz
= 470 pF: 133 kHz
= 390 pF: 160 kHz
