There must be resistance between OUTP and the power side power supply. *2 Specified substrate: 114.3mm 76.1mm 1.6mm, glass epoxy board. *3 Tj max=150C must not be exceeded. 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.
