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.

Truth Table FGIN PWMIN SENSE OUT1P OUT1N OUT2P OUT2N Mode L L L H H OUT1 → 2 drive H L L H H L L OUT2 → 1 drive L H L H H H H L H H H L Regeneration mode (low side regeneration) L H L H H H L H H H H L Current limiter (low side regeneration) Note 1 : For the SENSE pin, the "H" state is 0.2V or higher. Note 2 : The IC goes to regeneration mode (no motor drive applied) when the microcontroller is reset (the output high-impedance state). Stresses exceeding Maximum Ratings may damage the device. Maximum Ratings are stress ratings only. Functional operation above the Recommended Operating Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect device reliability. |
