The constant-voltage drive mode output voltage (the voltage between the output pins) VO is determined by the
following formula. VO = (Vcont pin input voltage) × 2.4 (typical)
There are no restrictions on the relative magnitudes between the following voltages: VCC (control system supply
voltage), VS (motor supply voltage), and IN1/IN2/Vm (the input signal voltages).
