Three-phase logic truth table
Pin Assignment
• The condition with the upper gate = VH and the lower gate = UL corresponds to a state in which the upper FET is
• The HP output is an open collector output. Therefore, “H” level corresponds to an open state.
turned ON when the VH pin is connected and the lower FET is turned ON when the UL pin is connected.
