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. Monolithic Digital IC Low-Voltage, Low-Saturation Bidirectional Motor Driver Stresses exceeding Maximum Ratings may damage the device. Maximum Ratings are stress ratings only. Functional operation above the Recommended Oper ating Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect device reliability.
