Caution 1) Absolute maximum ratings represent the value which cannot be exceeded for any length of time.
Caution 2) Even when the device is used within the range of absolute maximum ratings, as a result of continuous usage under high temperature, high current, high
voltage, or drastic temperature change, the reliability of the IC may be degraded. Please contact us for the further details.

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).
