Functional Description
The Supertex FP0030 can be considered as a normally
closed switch controlled by a switch control (please refer to
the block diagram). The switch control monitors the voltage
drop across terminals A and B. If the voltage difference is
greater than ±1.5V, the switch will start to open. Once in the

flows through the switch to detect if the high voltage is still
present or not. The switch will not close until the voltage
across terminal A and B drops below ±1.5V.
