(1) Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
(2) VDRAIN pin voltage with respect to high-side gate pin (GHx) and phase node pin voltage (SHx) should be limited to 102 V maximum. This will limit the GHx and SHx pin negative voltage capability when VDRAIN is greater than 92 V.
