Changing the predefined current (during acceleration)
Even when the reference voltage is increased, the regulator remains in Discharge mode for four CK
cycles and then it enters Charge mode.
The average current value becomes lower than the set current value because of the peak current detection
method. It should be noted that the average current value changes, depending on the motor characteristics.
Calculation of the Internal Oscillation Frequency
The OSC oscillation frequency can be approximated by the following equation:
fOSC = 1/{0.523 × (COSC [F] × 3700 + COSC [F] × 600)} [Hz]
Reference Voltage Generator
In constant-current mode, the peak current is determined by the Vref voltage, as follows:
IO = Vref/RS × 1/6 [A]
