*1 : The maximum power transistor ON resistance(RDSON) is 360mΩ(design guarantee value).
Note : The value of these characteristics were measured in Our test environment. The actual value in an end system will vary depending on the printed circuit
board pattern, the components used, and other factors.
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.
