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