The LV148 specification says that the range is between 24V and 52V, so you’ll need pre-drivers and power transistors that can handle the voltage at the switching-power nodes, plus some margin for potential spiking (inductive switching, load dumping, back EMF). In the 48V case, transistors and drivers that can handle at least 100V on the power .
