Electrical Characteristics (continued)

Specifications with standard typeface are for TJ = 25°C, unless indicating that type applies over full operating junction

temperature range. VVIN = 48 V, VVCC = 10 V externally applied, RRT = 15 kΩ, RDLY = 27.4 kΩ, VUVLO = 3 V, VOVP = 0 V unless

otherwise stated. See
